I am trying to install IR8 using ACU and I keep getting an installation error when the client attempts to install the Microsoft Visual C++ Redistributable Package. The error says: There was an error launching the Microsoft Visual C++ Redistributable Package install. When I click OK, I get the following message: An unknown installation error occured: 0x00000001(1). I currently have IR7 installed and I have edited the install.ini file to do a silent upgrade with no prompts. This same process worked great for our upgrade from IR6 to IR7. I do have the install.ini set to install both NICI and NMAS. Any thoughts or ideas? Thanks for your help.
