Question

I have just downloaded VS Community 2015 onto my desktop PC which is running Win10.  Successful download and installation but if I try to open a Project (the first Project I have ever tried to open) I get an error "Error loading type library/DLL. Exceptionfrom HRESULT:0x80029C4A (TYPE_E_CANTLOADLIBRARY).

I have tried uninstallig and reinstalling get no errors during installation but the problem still persists. 

Any ideas on what the problem might be?

Hi, Martin

Thank you for your post. I’m sorry that you can’t open a project on VS 2015. We will try to help you to fix the issue. It is related to loading type library/DLL.

Firstly, could you please tell us what project did you running on you PC? It would be more helpful if you could provide us more detailed error information about the project.

Secondly, since that you just downloaded the VS community 2015, the issue might occur due to the installation of VS, so we need relevant log to help you analysis the problem.

Please use  http://aka.ms/vscollect to gather the installation logs. After using it, you will find vslogs.cab from %temp% folder. Please upload the file tohttps://skydrive.live.com/ and share the link here.

Hope it helps.

If you have any concern, just feel free to let me know

Hi

I have gone to the "Walkthrough:Create a simple application...".  Changed the Color Theme that worked OK.
The next step was to Open a New Project and all that happenes is that I get the Error message as quoted in my question.

Have run aka.ms.

The Command Prompt window opens.  Loads of info. scrolls up and then the Command Prompt window closes.  I can not find vslogs.cab anywhere on my C: drive.  Did a search in local disk (C:)  "type:cab modifiedtoday" no files found.

@Martin,

So have you checked the %temp% folder? Just type %temp% in your file explorer:

And you will be redirected to the local log folder. Please try search for VSlogs.cab. If you cannot find it, which means the collect.exe tool crashed. We may need to manually check your logs.

But all those logs are for us to troubleshooting this case. I think you need to take some other important steps first:

1. Verify your installer. Visual Studio installation can have web installer and ISO installer. If you meet installation problem I recommend you use the ISO format first. Download it from official site and then you can refer to this page:https://www.visualstudio.com/en-us/downloads/visual-studio-2015-iso-sha1-vs.aspx

With the sha1 code from the above page we can use fciv.exe to verify our ISO sha-1 value. This can help us make sure our installer is OK.

2. Since you have error in Visual Studio. When you are sure your installer is good. Try run it to repair your current installation. This may fix your problem.

3. Some other steps which may helpful before we repair(Actually you should do it before the installation)

• Clear your %temp% folder before the installation
• Turn off any anti-virus software
• Make sure to run your installer with Admin privilege
• Make sure your OS is update to date.(With all updates applied)

Please try the above steps and feel free to tell us the result.

Best regards,

Barry

Hi Barry

Thanks for the info.  I did a clean install of Win10 and then VS, now everything works.  So I guess it was some registry problems as I recently upgraded to Win10 fron Win8.1 and the registry has not been touched since before I upgraded to Win7 years ago.
