Why it’s not possible to restore PG5 backup files created with PG5 2.3.196 or newer, into older versions of PG5 like PG5 2.3.195?
FAQ #102072
If a PG5 backup file created with PG5 2.3.196 or newer PG5 version, should be restored with an older PG5 version < 2.3.196, then an error message ‘ZIP File read error’ will be displayed and it’s not possible to restore the file into PG5 2.3.195 directly in to PG5.
Workaround:
As a workaround, the .zip PG5 backup file can be unzipped with Windows Explorer and the contents copied/pasted into the PG5 project directory. The project can then be handled with all PG5 2.3.xxx versions.
Reason why the error is shown:
The reason for this incompatibility is that in PG5 versions >= 2.3.196 a new 32-bit ‘zip tool’ has been integrated which can compress more than 65535 files into one zip file. In PG5 < 2.3.196 a 16-bit ‘zip tool’ is integrated which can ‘only’ compress up to 65535 files, and this 16-bit ‘zip tool’ cannot open the 32-bit zip file.
