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 unpacked using Windows Explorer and the contents imported into the PG5 project using ‘Import Device’ or ‘Import Project’ from the PG5 Project Manager.
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.
