Outlook plug-in installation error: Exception from HRESULT: 0x8004063D

Question

I have a plug-in that is installed via ClickOnce(?) and works fine on 40 or so different end user PCs without an issue. However, there are 2 PCs that it just won't install on. I have been unable to find a corresponding error code on the interwebs.

Here is the full "details" of the installation failure:

Note: VSTO is 2010 and .NET 4.0. 

Answer 2

Hi Josh,

Thank you for posting.

From the description of your post, the tow PCs' configuration environment must be different with others. Actually, I haven't encountered the exception before. Please try the following approaches to see whether they can resolve the problem:

1. Reinstall .NET 4.0 framework

2. Close other applications during installing the clickonce package.

3. You can also try the method mentioned in the article:

Hope this can help you and just feel free to follow up after you have tried.
