The Visual C++ 6.0 Processor Pack is not compatible with Visual C++ Service Pack 6. If you install the Visual C++ Service Pack 6 on a machine on which the Processor Pack is already installed, the Processor Pack functionality will become unavailable. Likewise, if you install the Processor Pack on a machine on which the Service Pack 6 is already installed, the Service Pack 6 will no longer function.
The Processor Pack is a nonlocalized component, which will install and work correctly with localized versions of Visual C++ 6.0. However, it is important to note that the Setup program overwrites your localized compiler files with an English version. Error and warning messages will occur in English.
There is no uninstall; you must uninstall Microsoft Visual C++ 6.0 and manually remove the remaining Processor Pack files.
The Processor Pack documentation is installed in the VC98 folder. MASM version 6.15 is installed in the bin folder located in the VC98 folder.
