Issue

Attempting to install an .msp file (in my case Citrix XenApp 6.5 RollUp7) it fails to install with the following error message.

Error Message

msp error

Troubleshooting Steps

Run the msp with the verbose logging switch for example:

.\XA650W2K8R2X64R07.msp /L*v C:\Temp\RollUp7.log

2. Have a look in the C:\Temp\RollUp7.log file and you’re looking for the highlighted in red below “C:\Windows\Installer\d5c63.msi

3. Browse to C:\Windows\Installer\ folder (hidden protected OS folder) and rename the .msi to .old mentioned in the log file.

4. Re-run the .msp install

5. This time it will prompt for the original msi files, in my case it was the mps.msi
