I am unable to use the buildin function to register my templates on WinXP Pro SP2 or Vista Ultimate. Under Vista, Clarion 6.3 starts up, but the register function fails (returns 0). Under XP, Clarion 6.3 does not even start up. In both cases, I am using the Clarion detection dialog, and specifying a variable to capture the path. It contains the base Clarion 6.3 path (e.g. C:\CLARION63). I have tried both marking the TPL files to register, and adding the Queue template file script element for each, but the Register script element fails in all cases (I have 4 TPL files to register, and all 4 fail no matter what I try). Any ideas would be helpfull.
