Hello Shark007, I had just recently known about your awesome addon and what it can do to shrink my uacd further, although I am having problems integrating it as an addon. How can I make your acrobat lite installer into an addon? I tried wordup48's method but my UACD ends up looking for the ar811lite.exe file. Any suggestions to resolve the issue? Tried doing it twice but still the same, it looks for the file that exists where its supposed to be. I checked in i386/svcpack and sure enough, the ar811lite_eng.exe file was there. Below are the entries_ar811lite_eng.ini file settings: [general] builddate=12/21/2007 description=Installs Adobe Reader 8.1.1 language=English title=Adobe Reader version=8.1.1 website=http://www.msfn.org/ [GUIRUNONCE] %windir%\ar811lite_eng.exe cmd /c del /Q/F %windir%\ar811lite_eng.exe [dosnet_files] d1,ar811lite_eng.exe [txtsetup_files] ar811lite_eng.exe = 1,,,,,,,1,0,0 Thanks!!!
