Arnold,Yes you can replace those files(they are M$ files and have nothing to do with Adobe).I know the MSVCRT10.dll file does get damaged/altered when installing or removeing some softwear. When I took Lightwave off my system,it took several important M$ dll's with it(crap). Do a search on Google for ".dll"...there is a site that has most M$ dll's for download. PLEASE NOTE: This is a very legal thing to do as you are replaceing missing or damaged OS files. They have nothing to do with Adobe(or any other softwear programs),and will not allow a user to "crack" a warze version. However,you said..."learned to live with for years"...sounds like it's time for a reformat,and clean installe of your OS and all programes anyway. SWAMP
