Configuring the XRTK in a new project raises UnauthorizedAccessException exception

[SimonDarksideJ]

XRTK - Mixed Reality Toolkit Bug Report

Describe the bug

In new projects, or with fresh configuration, the editor reports UnauthorizedAccessException errors in the console. This doesn't happen for all files, only a single one for each package (but may simply stop at the first)

Likely cause is the files are maybe trying to copy twice, as all the files mentioned are already present and copied

To Reproduce

New Project

1. Create a new project
2. Use the XRTK seed package to install XRTK
3. Upgrade XRTK to the latest preview
4. Install the latest SDK preview
5. Observe the profile copy after the package installed
6. See error in console

Existing Project

1. Open Project project
2. Upgrade XRTK to the latest preview
3. Install/upgrade the latest SDK preview
4. Close the project and delete the library folder from root and the XRTK.Generated from assets
5. Re-open the project
6. Use the "Mixed Reality Toolkit -> Packages -> Install XRTK.SDK package assets...
7. See error in console after copy complete

Expected behavior

No Errors

Actual behavior

Below error is logged to the console, the same happens for all the other packages which have assets to copy.

Your Setup

• Operation system Windows 10
• Unity Version 2019.1.14
• XRTK Version 0.2.0-Preview.69

[StephenHodgson]

Are you installing the preview packages by default?

I suggest installing only the previews and not upgrading to the latest from anything prev to 0.2.0

The latest seed package installer from the release downloads should have the preview toggle

[SimonDarksideJ]

It happens even if I'm only using the previews, as described in the "Existing project" replication steps

[StephenHodgson]

Both examples sound like they're moving from 0.1 to 0.2. Just want to clarify

[StephenHodgson]

Also, what existing project are you using? Is this something you can share so I can better understand your setup?

[SimonDarksideJ]

Replication 1 is from 0.1 to 0.2 effectively as it starts with the 0.1 seed, but the scene / toolkit is NOT configured. The packages are simply updated prior to use, as stated in the replication steps.

And AS STATED in the replication steps, this is a clean, brand new project with no content.

[StephenHodgson]

Why are you installing the 0.1 packages then moving to 0.2 when the seed provides a way to cleanly install the 0.2 previews?

[SimonDarksideJ]

@FejZa can you attempt to replicate this issue as Stephen is having troubles getting the error.

Mine is a completely brand new installation, so should be representative of what most people will have.

[StephenHodgson]

I don't think most people are installing the 0.1 release and upgrading to 0.2.

For existing projects I might suggest removing the xrtk then doing a clean install of 0.2?
