Notes on migration from the 32-bit version

Uninstall the current 32-bit version and reinstall the 64-bit version. License key and setting items must be re-installed.
If the destination folder is standard
"C:\Program Files (x86)\RectPacker\" to
"C:\Program Files\RectPacker\".
This will be changed.

 

In the future, we will move to 64bit version only.

Even with 64-bit versions of Windows, 32-bit applications will run without any problems at all. However, since only 64-bit versions of Windows are being sold, we are shifting to 64-bit applications in order to keep up with the times. 64-bit compatibility will be partially supported through 32-bit processes for backward compatibility with license keys issued before April 22, 2023.

 

Advantages and disadvantages of the 64-bit version

There are no particular advantages. The calculation speed remains the same. However, if the number of parts in a 1D layout calculation exceeds 2000 or so, the 32-bit version may run out of memory. In such a case, 64-bit will work more stably. The disadvantage is that the memory usage will increase even if the calculations are the same.
