I've just installed ACM'13 on my notebook and I can't open it. When I try to do it, the start window show up, it starts to load components and after that it stuck in "Loading" loop (I guess so, because I have a polish version). Also I can't see any application or proces in Task Manager related with that. There were not problems or errors during instalation. Oh, before that I'd installed only AutoCad 2013 and there was the same problem.
Few weeks ago I had Win7 and it worked perfectly. Any ideas?
Welcome to the community. Sounds like a license issue to me.
You might see if the licensing even exists:
C:\Documents and Settings\All Users\Application Data\flexnet\adsk*.data
Delete those and relaunch.
See if this file exists (or an adlm log file with it.)
C:\Documents and settings\All Users\Application Data\Autodesk\ADLM\ProductInformation.pit
You might need to blow it away and reinstall.
I would like to check your startup log file, see if we can get any helpful info.
You can find the log file under C:\ProgramData\Autodesk\Adlm\AMECH_PP2013XXXAdlm.l
BTW, what's your OS now?
