When opening a project with Installshield 2020 I get the following error message: Object reference not set to an instance of an object

When opening a project with Installshield 2020 I get the following error message: Object reference not set to an instance of an object.

This error is related to TFS 2015. Because our SCC provider is TFS 2015 via Visual Studio Team Foundation Server MSSCCI Provider 2013. 

My question is how to find the cause of this error message?

Reinstalling of Visual Studio Team Foundation Server MSSCCI Provider 2013 didn't  help.

Any ideas?

Hi @abl_nedgraphic ,

Few suggestions to get rid of object null exception:

  1. Try to open Visual studio in Administrator mode
  2. Make sure whether it is because of low disk space
  3. Try to clear the cache on this client computer:

    • Close any open instances of Visual Studio.
    • Browse to the following folder: C:\Users\username\AppData\Local\Microsoft\<TFS fOLDER>
    • Delete the contents of the Cache directory, including all subfolders.
  4. Use the IP address of TFS instead of server name if you have used server name.

Thanks,

Jenifer

Hi Jenifer,

I already tried to empty the cache folder.

This problem has something todo with "Microsoft Team Foundation Server MSSCCI Provider", but unfortunately. you are not familiar with this problem. As work-around I can use Visual Studio to check-out the msi., as long as the integrated solution with Microsoft Team Foundation Server MSSCCI Provider not works.

Kind regard,

Adrie
