Oracle Forms

Config:
Forms [32 Bit] Version 11.1.1.3.0 (Production)
Win7 Prof. 32-bit

I read 199175.1 FRM-18122 and FRM-18127 When Opening Forms Builder or Running a Form stating

+Although more common in older versions of windows, check the length of the value of FORMS_BUILDER_CLASSPATH. If it is much larger than 512 characters, this could be the problem.+


And yes my FORMS_BUILDER_CLASSPATH is longer, it's

C:\Oracle\Middleware\as_1\jlib\frmbld.jar;
C:\Oracle\Middleware\as_1\jlib\importer.jar;
C:\Oracle\Middleware\as_1\jlib\debugger.jar;
C:\Oracle\Middleware\as_1\jlib\utj.jar;
C:\Oracle\Middleware\as_1\jlib\ewt3.jar;
C:\Oracle\Middleware\as_1\jlib\share.jar;
C:\Oracle\Middleware\as_1\jlib\dfc.jar;
C:\Oracle\Middleware\as_1\jlib\ohj.jar;
C:\Oracle\Middleware\as_1\jlib\help-share.jar;
C:\Oracle\Middleware\as_1\jlib\oracle_ice.jar;
C:\Oracle\Middleware\as_1\jlib\jewt4.jar;
C:\Oracle\Middleware\as_1\forms\java\frmwebutil.jar;
C:\Oracle\Middleware\as_1\forms\java\frmall.jar

That's what the installation put there.

Is the length really the reason? (That means Win7 is older OS?)

In principle Forms-Builder works, but without Help and there was no need fpr the debugger, so far.

Any suggestions for a solution? THX
