System 7.x: Compatibility Checker Error Messages

Since the Compatibility Checker was made into an application with version 2.0, which comes with System Software 7.1, and it's newer version 7.1.1, which comes with System 7 Pro, you no longer receive HyperCard error messages.

If you are using the HyperCard based Compatibility Checker that comes with System 7.0, the following information lists common error messages.

Error: "New file format requires a new version of HyperCard."

After you convert the Compatibility Checker stack to HyperCard 2.0 format, you cannot run it under earlier versions of HyperCard. This converted stack needs system software 6.0.5 or later, and HyperCard 2.0 or later. If you do not have the required software, follow these steps:

1. Copy the HyperCard application and Home stack from the System 7 "HyperCard" disk, and the Compatibility Checker from the "Before You Install" disk to your hard disk.
   
2. Start the Macintosh with the System 7 "Disk Tools" disk.
   
3. Double click on the Compatibility Checker. Because the Compatibility Checker can check for compatible INITs and CDEVs only in the System Folder of the startup disk, it won't check the System Folder on your hard disk. But you can still check the applications on your hard disk.

Error: "This stack has not been converted. It must be converted before it can be modified."

Manually copy the Compatibility Checker stack to the hard disk before launching it.

Error: "You need an additional 193K of space on 'Before You Install System 7:Compatibility Checker 1.0' to use Compatibility Checker"

The Compatibility Checker displays this message when running from an unlocked floppy disk. The only option is to quit, lock the floppy disk, and try again.
