I installed Act 2010 with no problem. Then when I tried to install update I keep getting a 1603 error. I had trouble uninstalling so I downloaded uninstaller and reinstalled. It again went fine until I tried to install update and then got 1603 error again.
Please see your Private Notes for a link to download the fully updated installation files for Act! 2010. Using this method you will not have to 'update' after installing the main program.
I am also having this error on 2 Windows 7 32 bit machines. The SP1 update worked on the other 2 Windows 7 32 bit machines. I have tried all other avenues. Could you send me the link to the sp1 full installer please.
