iamnew 10 Posted July 11, 2018 Hi all, I'm running 2002 and just tried to open it again and it failed.....missing file. The missing file is "ac1st15.dll" I don't know what happened to it. Looked everywhere. The only thing I can do now is hope someone could send it to me. Thanks Quote Share this post Link to post Share on other sites
rkmcswain 72 Posted July 11, 2018 Did you just install an old version of Norton AV also? This used to be linked to Norton removing this file: https://knowledge.autodesk.com/support/autocad/downloads/caas/downloads/content/file-to-resolve-error-after-norton-antivirus-E2-84-A2-2003-installed.html?st=ac1st15.dll Perhaps another AV did the same thing? Was it working fine up to some point? If so, what changed? Quote Share this post Link to post Share on other sites
iamnew 10 Posted July 11, 2018 Have not installed Norton......but had to reinstall "TotalAV". Don't know if it's related to my problem.....will take a look. Thanks for your reply and will let you know what happens Quote Share this post Link to post Share on other sites
iamnew 10 Posted July 11, 2018 I wasn't able to find anything after looking at my AV Quote Share this post Link to post Share on other sites
iamnew 10 Posted July 11, 2018 Guess what now? Another missing file "acutil15.dll" Now I'm wondering how many more are missing? By the way, I got "ac1st15.dll" back Quote Share this post Link to post Share on other sites
