If you are having trouble running the JTX 9.4 Beta 1 Post-Installation on Windows 7, UAC may be the culprit. Here is my platform information:
Windows 7 Enterprise, 64 bit
SQL Server 2008 64 bit
ArcSDE for SQL Server, Advanced/Enterprise
When you get to the screen for creating the connection to the JTX Repository, and click the "Finish" button, you will get an error that pops up in a window that says:
Execption from HRESULT: 0x800A0046 (CTL_E_PERMISSIONDENIED)
The JTX tables will be created in the database, but if I you try to Add JTX Database in ArcCatalog, you will get the same error.
The solutions are as follows:
1. Drop the User Account Control settings in Control Panel. I dropped it to the lowest setting, but one notch lower might work.
2. Run the Post-Install tool as "Administrator"
3. Use C:\program files\jtx\bin\jtxadvancedsettings.exe to change the Database Folder path to a different location. You could, for example, create a folder called C:\JTX, then run the post-install tool again.
