Symptom and Scope
A project created with GX Developer 7 cannot be selected in GX Works2 through Project > Open Other Data > Open Other Project. The project directory appears dark rather than yellow, and GX Works2 does not open it.
Before converting anything, confirm whether the source application was GX Developer or GX IEC Developer. The evidence does not establish that projects from those applications use the same migration path.
Confirmed Resolution
The successful correction was to copy the complete project from the CD-ROM to the computer hard drive and open the hard-drive copy. This isolates the project from the optical-disc location without changing its GX Developer 7 content.
| Project location | Observed result | Decision |
|---|---|---|
| CD-ROM | Project could not be opened | Do not treat this result alone as a format-conversion failure |
| Computer hard drive | Project opened properly | Use the copied project as the working copy |
Opening Procedure
- Copy the project files from the CD-ROM to a directory on the computer hard drive.
- In GX Works2, select Project > Open Other Data > Open Other Project.
- Browse to the copied directory and select the actual project.
- Verify that the hard-drive copy opens before attempting any version conversion.
Preserve the original CD-ROM files and make changes only to the copied project. Successful opening of the hard-drive copy confirms that the original failure was associated with opening from the disc location rather than a demonstrated incompatibility with GX Developer 7.
If the Hard-Drive Copy Still Does Not Open
Recheck that the project was created with GX Developer rather than GX IEC Developer and that the actual project was selected inside the directory. A proposed fallback is to open the project in GX Developer 8, save it under a new name, and then open it in GX Works2. This conversion path was suggested but was not required or verified in the resolved case.
FAQ
Why is my GX Developer 7 project dark in the GX Works2 directory?
The dark directory coincided with a project being opened from CD-ROM, but the visual state alone does not prove a version incompatibility. Copy the complete project to the hard drive and try the same open command again.
Can GX Works2 open a GX Developer 7 project from a CD-ROM?
In the documented case, the CD-ROM copy did not open, while the same files opened properly after being copied to the computer hard drive. Test the hard-drive copy before converting the project.
Must I convert a GX Developer 7 project with GX Developer 8 first?
Not in the resolved case; copying the files to the hard drive was sufficient. If that fails, opening and resaving under a new name in GX Developer 8 is a proposed fallback, not a confirmed requirement.
