SlimDx.dll??

[CharlesCardigan]

I keep trying to install medlaunch, and when i get to the part when it asks to pick a directory i choose the unzipped file of mednafen on my desktop. It tries to load and then it says it has stopped working and closes. So i check the exceptions and this is what it says. Been trying to search for a solution but cant really seem to find anything. So i have resorted seeing if anyone on here has solved this. help would be really appreciated.

Can you check your anti-virus logs? The exception is basically saying that the SlimDX.dll cannot be found (this is located in the MedLaunchdir\lib)

If when you look in that folder you cannot see SlimDX.dll it is possible your anti-virus/security software is detecting it as something untoward and deleting it I guess...

[CharlesCardigan]

I checked the folder and i see SlimDx.dll in there.

[Asnivor]

And do you have an anti-virus installed that you can check the logs of? Perhaps the file has been 'cleaned' and that is why it isnt loading properly?

[CharlesCardigan]

The only anti virus i have is the stock windows defender that windows 10 comes with. Should i try uninstalling medlaunch and then deactivate defender and try again?

[Asnivor]

Yeah, thats worth a try. Make sure once you have disabled defender that you re-download the latest medlaunch zip, then extract that.

[Asnivor]

Also, you can try right-clicking the medlaunch executable and 'run as administrator'. Just in case there is something weird happening.

[CharlesCardigan]

It still came up as the same exception. The steps i am doing is downloading medlaunch, extracting the files to a file on my desktop called mednafen gui, then i run the exe it bring up the loading screen and asks if i want the auto updater, then it says to find the directory for mednafen so i go to the desktop folder which is mednafen-0.9.47-win64 (pretty much the extracted mednafen file) and when i press select folder then it loads a little and stops working. mednafen works fine so i know that the emulator itself is configured ok. Not sure if maybe im doing something wrong

[Asnivor]

I dont think you are doing anything wrong. At the point that it is crashing medlaunch is starting up and trying to load the slimdx dll. Not sure why it is erroring for you at this point.

Is your windows 10 x86 (32bit) or x64?

[CharlesCardigan]

i have x64

[Asnivor]

Hmm. If you navigate to your MedLaunch folder, in the 'lib' directory, can you right-click on SlimDX.dll and go to properties?

At the bottom of the 'General' tab is there any sort of security message saying the file is blocked?

[CharlesCardigan]

No it doesn't say anything like that. The only thing at the bottom is Attributes

[Asnivor]

Ok, i'll have to get an x64 windows 10 VM up and running at some point soon and see if I can replicate the problem.

[CharlesCardigan]

Thanks, appreciate you trying to help

[SteveBurgess]

You could try installing SlimDX from here

https://slimdx.org/download.php

I'd try the x86 version first. Seems to have fixed a similar issue here https://github.com/Koenvh1/ets2-local-radio/issues/18

[CharlesCardigan]

That fixed the problem, Thank you, really appreciate the support on this.

[Asnivor]

@CharlesCardigan great news.

I'll look to ship the installer with the next release and have medlaunch prompt the user to auto-install it when this exception is generated.

Thanks so much for the feedback.

[Asnivor]

Tested on Win10 x86. Looks like slimdx actually just needs vcredist_x86.exe installed.

https://www.microsoft.com/en-gb/download/details.aspx?id=5555

I will ship this with each release, and check that it is installed everytime medlaunch starts (with the option to auto-install it before proceeding).

[Asnivor]

As of next release, MedLaunch ships with the required vcredist_x86.exe file and user is prompted to auto-install this if the system lacks it.
