Had a customer wanting to run reports on an older voice-mail system so had to install ASA 5.2 (Avaya Site Administrator) but found it repeatedly crashed in Win 7, fortunately came across this useful snippet of information on a support forum. Delete the uxtheme.dll from C:\Program Files\Avaya\Site Administration\bin and it then runs properly.
Thanks for the tip. I had the same problem with Site Administration 5.2.17. Your tip worked for me on Windows 8.1
