VSTS 2010 Beta Installation and Error 1500. Another installation is in progress.

  • Article

Yesterday I installed the Windows 7 Enterprise RTM version on my Laptop, followed by VSTS 2010 beta, and SQL 2008. Everything appeared to be going well, but then later this morning I tried to install some other application and I got a variety of errors reminding me that “another installation is in progress” and I should first finish the installation before attempting to install another program.

After some un-successful attempts to figure out what program caused the problem and deleting the Registry key indicating “InProgress” I was pulling my hair because the registry key was appearing again every time shortly after deleting it, I guess to prevent people like me to mess with it ;-).

Long story short, finally I got the system to comply with my request to install another program by

  1. Disabling the “Windows Installer” service
  2. Rebooting
  3. Enabling the “Windows Installer” service
  4. Rebooting

The message that I got when trying to install the sample database indicated that the Visual Studio Tools for applications 2.0 was still in progress and would have to be re-run (see below).

It seems that the installations now succeed…. Took me some time to figure it out, but I hope that I can help some of you to avoid a similar odyssey since the solution really just took the time for two reboots…..

 

Have fun….
