I still get 1601 error which is a MS INstaller problem. I have done everything: re-register, install new installer, bypass normal startup, run fix it programs to fix hard disk errors and optimize perfomance, etc. and still can't get updates to install. I have tried all the Installer suggestions wihout any luck. Reader is the only program that has an install problem. Other updgrades and installs are working ok. Any suggestions are appreciated
What is your Windows version?
What is your Windows Installer version?
What is the full 1601 error message?
Windows version: 6.0 SP2
MSI Ver 4.5
Error in adobe is 1601. Also says: The Windows Installer Service could not be accessed. This can occur if the Windoows Installer is not correctly installed.
Information on how to fix was obtained form Microsoft and other forums. Tried them all -- and they don't work.
