PRB: Public Property of a Class Module Can't Be Set to True

• Professional and Enterprise Editions of Microsoft Visual Basic, 16-bit only, for Windows, version 4.0
• Windows for Workgroups, version 3.11

SYMPTOMS

After installing Visual Basic version 4.0 over a previously installed Visual Basic version 3.0, the Public property of a class module cannot be set to True. When you attempt to set the Public property of a Class module to True, the following error message appears:

   The Public property for Class Class1 cannot be set to True. You do not
   have an appropriate license to use this.

CAUSE

There are two possible causes for this problem:

• The registry contains some entries for version 3.0 that the version 4.0 setup program did not remove.

  -or-

• The registry file, Reg.dat, is over 64K. The version 4.0 entries may be ignored.

RESOLUTION

Exit from Windows for Workgroups; from the MS-DOS prompt, find the Reg.dat file and rename the file to Reg.old. Start Windows for Workgroups and reinstall Visual Basic to rebuild the registry.
