Today I found the service "FLEXnet Licensing Service" listed and was wondering what was using it. I decided to stop it and disable it. While going about my business today I noticed that another problem disappeared from my PC. Once I went to look at a docuemnt in acrobat 9 it told me I had to reinstall due to a problem. I remembered I disabled the "FLEXnet Licensing Service" service this morning. So I change the service from disable to manual, opened Acrobat with a document and my PC hung with the hard drive light on constantly.
I just scoured google with the term FLEXnet Licensing Service and hanging and noticed some threads.
Is this a known issue?
