Describe the bug
When i try to use the built plugin (commit/156cc32 binexport12_ida64.dll bindiff8_ida64.dll) in ida pro 9.1

Error while diffing: Export of the secondary database failed: Error executing: '"C:\IDA Professional 9.1\ida64.exe" "-A" "-OBinExportAutoAction:BinExportBinary" "-OBinExportModule:C:\Users\User\AppData\Local\Temp\BinDiff\secondary\test.exe.BinExport" "-OBinExportAlsoLogToStdErr:FALSE" "-OBinExportX86NoReturnHeuristic:FALSE" "C:\v3\test.exe.i64"'

while it does not work as i'd expect it with the bindiff app or plugin directly, it seems to run when using the binexport plugin and then compare like:

Can confirm getting this with IDA 9.3

Someone needs to update it. It wasn't updated since eternity so obviously it doesn't support a newer format.

Yeah, I am (veeery slowly) working on an update. Use the workaround of exporting manually from IDA for now.

Note that the latest green builds for both BinExport and BinDiff have updated binary artifacts you can use:

• https://github.com/google/binexport/actions/runs/30012552722
• https://github.com/google/bindiff/actions/runs/32164035410

Binaries are for Linux (x86-64, AArch64), Windows (x64, ARM64 except Binary Ninja) and macOS (Universal).
