You havent said what the application is, but it must be looking at HKLM because its instructed to, i.e. the program either has hard coding to HKLM or a pointer/file is set to read HKLM. Alternatively, its quite usual for a program to look at HKCU/HKU entries, not find what it wants and goes to the default HKLM entry. Have you contacted the author(s) of the application?

Hi All, The issue is about application reading the entries from HKCU in windows 7 or vista OS. We have a virtualized application, which suppose to get the registry settings from HKCU. But, the application is not at all looking up the HKCU registry entries, instead it is looking at HKLM and throqing error "registry key not found". Windows logged in user is "Administrator" and UAC is turned on for user. is this behavior happening because of some secuirty issues in windows 7 or Vista? Thanks Venkatesha

it's a C#.net application, which is reading the COM registry entries. When the application is getting installed registry entries are made to HKCU. But, the application is looking for entries in HKLM. Since it doesn't find entries in HKLM, application fails and exits. this issue is not happening always. this issue is sporadic. there is no definite pattern when the issue occurs and when it works.

Hi, Since the application is developed by C#.net, I recommend to contact MSDN forum. http://social.msdn.microsoft.com/Forums/en-US/category/visualcsharpNiki Han TechNet Community Support
