Problem
When installing or uninstalling a program you get the following message:
“Error 1722. There is a problem with this Windows Installer package.”
Solution
Try the following:
- Set Data Execution Prevention (DEP) to it’s default setting.
- Re-register the Windows Installer
- Open a Command Prompt as an Administrator.
- Type msiexec /unregister and press Enter.
- Type msiexec /regserver and press Enter.
- Close the Command Prompt.
- Download and install Windows Installer 4.5
I’ve read several solution with thousand of lines in HP forum but none of them worked for me. Your simple solution worked perfectly. Thank you.
