I was installing SQL Server Management Studio Express 2005 on my vCenter server to run a clean-up when I found that I was getting this error:
The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 29506
In order to run the software, you’ll need to run it as an admin from a command prompt, seeing as how you can’t right click and run the software as an administrator.
- Open up an elevated command prompt by right clicking on CMD.exe and choosing to Run As Administrator
- Browse to the location of your .msi file and type it’s name in. My location was at C:\Users\Dan Lee\Desktop\sql.msi (I renamed the file to sql.msi for the sake of ease).
- That should it. The software will run and install without the error now.
Let me know what else you find on this, but this is pretty straight forward.
