WMF 5.0 on Windows 7 - PackageManagement appears not to be present?

[pfmoore]

I've just installed WMF 5.0 Production Preview on my Windows 7 laptop. But I can't see any of the package management tools:

PS> get-module PackageManagement
PS> get-command Get-Package
get-command : The term 'Get-Package' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path

I didn't do anything special when downloading, I just ran the download file from the Microsoft site. I've looked for documentation clarifying whether I need to do anything more to activate the package manager, but can't find anything.

Do I need to manually install OneGet separately? If so, where do I get it from? The links here point to the WMF 5.0 file I installed...

@pfmoore Can you double check you installed from http://www.microsoft.com/en-us/download/details.aspx?id=48729? if the issue persists, please contact @jianyunt and @quoctruong directly.

[quoctruong]

@pfmoore Can you try Import-Module PackageManagement? Also, can you double check that you have a PackageManagement folder in your module folders?

Thanks

[pfmoore]

@quoctruong Will do, but it'll have to wait till after the weekend.

@xumins Sure but how do I do that? I got it via the link at oneget.org (= the readme here) and that link is the same one you quote. If you mean uninstall, re-download and reinstall, then I can give that a go (again, next week) but I'd rather try the other suggestions first...

[xumins]

@pfmoore yes please try Quoc's suggestion first.

[pfmoore]

Hmm, ImportModule PackageManagement fails ("no valid module found") and there is no PackageManagement directory anywhere along $env:PSModulePath

Is there anything else I can try before reinstalling? Also, how do I reinstall? There's no WMF 5.0 entry in "Programs and Features". In "Installed Updates" there is "Windows Management Framework 5.0 Production Preview (KB3066439)" installed on 01/09/2015. Is that what I need to uninstall?

[jianyunt]

It looks PackageManagement and PowerShellGet are not installed because they are not in the list. Please uninstall previous installed WMF 5.0. thanks. By the way, did you install .net 4.5 before installing the WMF 5.0? If not, please do so. Which language of the OS are you using? From the date 01/09/2015, I guess it is not en-US, right?

[quoctruong]

Hi pfmoore, please make sure you had wmf 4.0 installed before installing wmf 5.0

[pfmoore]

@quoctruong I did. I think. I don't now (of course).

@jianyunt "Uninstall previous install". I'm not sure I understand. I currently only have one install, WMF 5.0 Production Preview. You want me to uninstall that, yes? And then what? Reinstall it from the MS website? I believe I installed .net 4.5 first (probably as a result of installing Visual Studio 2015). It's installed now, anyway (I'll double check tomorrow, but I'm pretty sure I already checked). My language is en-GB.

[pfmoore]

I haven't reinstalled yet, but I have re-downloaded the file and confirmed that the copy I installed is the exact same copy as I've just downloaded now. File and MD5 checksum are:

For what it's worth, I just installed WMF 5.0 Production Preview on Windows 7. I had a previous CTP which I removed and rebooted before attempting to install the Production Preview.

After installation and a reboot I do have PackageManagement and PowerShellGet installed in the C:Programs Files\WindowsPowerShell\Modules\ directory.

Just my experience so far...

[pfmoore]

OK. I have now uninstalled WMF 5.0 Production Preview. After doing so I found a WMF 4.0 in my "installed updates". I uninstalled that as well. I then confirmed that I had no working "powershell" command (I had some links left, and powershell.exe appeared to still be present on my PC, but if I ran it from cmd.exe, it simply terminated immediately). I could find no other WMF or powershell entries in either "Add/Remove Programs" or "Installed Updates".

I then reinstalled WMF 5.0 Production Preview, from the file Win7AndW2K8R2-KB3066439-x64.msu downloaded from the link on this site.

Result: still no PackageManagement module. I also don't seem to have a command line "powershell" link in my start menu any more. This is not a big issue to me, as I normally start powershell in ConEmu by directly running powershell.exe. I only mention it because it's a weird consequence that might be relevant.

I'm stuck now. I have a basically working PowerShell 5.0, but components seem to be missing that shouldn't be. I'd like to experiment with the new package management features but without them being present, I can't.

According to the PowerShell team at Microsoft you should layer WMF 4 on the machine before doing WMF 5 (check the release notes in detail as the requirement is buried in there).

Consider uninstalling WMF 5 and reading this article I wrote on how to reliably get WMF 5 installed on Windows 7 or Server 2008 R2: https://www.linkedin.com/pulse/article/poodles-through-burning-hoops-plan-powershell-5-win-7-darwin-sanoy

One small qualifier for Chocolatey. The "Chocolatey" PackageManagement plug-in installed by WMF 5 (even on production windows 10) is broken. The workaround is to install the full chocolatey client along side PackageManagement Chocolatey Provider. This shouldn't be necessary - which also means it may not be reliably fixing everything. At the point I have the full Chocolatey client installed, I might as well use it directly - it has better logging and is updated much more frequently. (Current Chocolatey PackageManagement plug-in is 16 months old and the open source project is not moving fast)

Thanks for the information. Just recently, however, I have got a new PC, so the issue is no longer a problem for me. Interestingly, however, the new PC was a straight Windows 7 install (with some corporate packages added, but as far as I know no WMF/Powershell upgrades) and I installed WMF 5 directly onto it, and the package management cmdlets were all present.

[pfmoore]

Hmm, reading your article I see

The bigger ouch is that you can successfully install WMF 5 on top of PowerShell 2 and when you reboot PowerShell shows version 5! So what state does that leave you in?

Maybe I'll do some further checking...

[DarwinJS]

Paul, I know the PowerShell team was targeting eliminating the WMF 4.0 requirement - so frankly I'm not sure if they have their story straight at this point. I advised that if it is a true dependency they should be blocking the MSU from installing if WMF 4 is not present on Win 7 or Server 2008 R2.

In reading that article (and the scripts linked to it) you can see how the lack of blocking for missing requirements (like WMF 4 and 5 not blocking when an insufficient version of dotnet is installed) is causing quite the aggregation of configuration sludge you need to discover and wade through for success.

It's disappointing that a technology targeted at making installations easy and automation ready suffers from being very non-automation ready and difficult to install correctly on a single workstation - let alone an fleet of enterprise machines.

[quoctruong]

Hi Darwin, to install the lastest WMF 5 that was just released, you don't need to have WMF4.

[DarwinJS]

Quoc, Could you please contact Keith Bankston at Microsoft - I have an email from him of Sept 3 saying that it is required - even after I brought the fact WMF 5 seems to install fine on top of PSH 2. Krishna Vutukuri was also copied on the email (but did not comment).

It would be great to find out WMF 4 is not required (and also remove it from the release notes for the final release if it's true).

D.

[quoctruong]

Hi Darwin, he's currently on vacation but I'll bring up this issues with him. We will fix the release notes accordingly. Thanks

Have the KB3066439 (WMF 5.0 prod preview). Tried to remove it from control but getting "An error has occurred. Not all of the updates were successfully uninstalled." The KB3066439 is still there. Anyway to remove it.

[copdips]

same issue here when uninstalling KB3066439 (WMF 5.0 prod preview)
