The Windows Installer Service could not be accessed.This can occur if you are running Windows in safe mode, or if the Windows Installer is not correctly installed. Contact your support personnel for assistance.
Above is the error when trying to install NAV 10.1.6.6000 on a Windows XP sp2 system. We have tried uninstalling and re-installing Windows Installer 3.1 (latest for XP), unregister and register the msi.dll. Also the msiexec.exe. System running in normal mode.
We have uninstalled NAV 10.1.5.x manually as it we were not able to uninstall thru Add/Remove.
Feedback and solutions appreciated.
Bob
