I just noticed I named this topic 'can't install...' when I ment to write 'can't run...' - just to get this straight.
I removed 2 of my 3 dimms and ran imgburn. On firt launch nothing happened - no error, no imgburn running in taskmanager though. On second run, the application started. So I had to assume you were right about the ram and wanted to find out how many dimms are affected. So I tried the other two dimms each alone and got the old error messages again. Only to be sure, I tried the first dimm again, expecting the application ro run but suddenly I receive the strange error messages again.
I then tried different setups of the 3 dimms togeter in different slots. The results are .. well strange say the least: with only 1 dimm inserted, the application would sometimes run, but never 100%. I still receive the weird errors or classic programm shutdowns regularly. With two or more dimms inserted, I wasn't able to get the application running at all.
I then tried memtest and ran several passes with all my memory inserted. After many hours I still had 0 errors. I am pretty much clueless right now..
