Abhishek,
First, let me say that I have Windows 7 64 bit and Gen 8.5 works fine in this environment.
Second, let's get to the problem. You may want to open a case with CA Support for this problem.
I reviewed the WER979F.tmp.mdmp file and see a few things to check in to.
1. The location of the Client Manager executable IEFCM85N.EXE shows to be executed from the C:\Program Files (x86)\CA\Gen85\Gen directory. But the directory that it gets installed to is C:\Program Files (x86)\CA\Gen85\Gen\VS100.
2. The version for the WRG850N.DLL shows to be 8.5.0.6643.
3. The dump shows that Attachmate Extra DLLs are being accessed.
I have the following questions from the above observations.
1. Was this Gen 8.5 installation installed or just copied from another machine? If copied, rename the Gen directory and then install from the CD or ISO.
2. Why was the IEFCM85N.EXE moved to the directory that it was not installed in?
3. The version of the WRG850N.DLL is pre-WKS85003. It is recommended that keep current on PTF, with a minimum of WKS85003 and WKS85004.
4. Has Client Manager ever worked on this machine? I am thinking not from your posts in this thread. If it has never worked, but it is accessing Attachmate Extra DLLs, you must have copied an iefcmn.ini from another machine. Is that right? If so, rename the iefcmn.ini and start Client Manager to see if it starts.
Here are some general questions/suggestions.
1. Have you tried starting the Client Manager with 'Run as administrator'?
2. Is the Windows ID you are logged on with have local Administrator rights on your Windows 7?
3. Do you have the Client Manager on a Virtual Machine or on a physical machine? If virtual, try installing Gen on the physical machine.
Again, you may want to open a case with CA Support.
