Update manager not working after update to 10000

Update manager not working after update to 10000

Hello,
After update to 10000 UpdateManager.bat not working. When I run UpdateManager.bat nothing happens. When I run .\scripts\UpdMgr.bat I recieve error:
The system cannot find the path specified.
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

What I need to do to resolve issue?

Windows Server 2012, MSSQL 2008

Regards,
Anton
