which version of OBIEE11g are you on? I dont think that windows 10 is yet supported/certified. Check the certification matrix for the compatible OS details. Better stick with certified OS version to have all working.
just a workaround (which may or may not work) try to open the admin tool using compatibility mode
I am not able to open OBIEE 11g Admin Tool
Be descriptive. Do you get an error?
As SunilSharma says you must check the certification matrix, last time I checked Windows 10 wasn't certified for the simple reason that Windows 10 officially exists only for few weeks now ...
126.96.36.199 added support to Windows 8 / 8.1, so if you are on 188.8.131.52 you can have a chance it works with Windows 10 as well, if you are on 184.108.40.206.* or earlier just forget, it will not work.
I installed OBI Admin Tool v. 220.127.116.11 on Windows 10 x64 in compatibility mode successfully.
If you load repository in offline mode everything works well as far as I know.
If you load repository in online mode and try to open logical object properties you get error: [nQSError: 46008] Internal error: File server/objectmodel/Src/SOMemoryRp.cpp, line 534.
Then the Properties dialog is opened but the datatype of all object is UNKNOWN.
I'm testing out Windows 10 (64-bit upgraded from Windows 7) and have a similar issue with the BI Admin tool version 18.104.22.168.150120.
What I found is that it finally does open after 15-20 minutes. During this time, the black, command line window is open as usual and CPU usage from this process is consuming about 30 percent. Once available, I have not encountered any errors and it appears to function normally.
