[Invisible-Boy]

I installed Xpra 5.0.4 setup.exe in windows 7. But it cannot work. An error happened, "SystemError: Negative size passed to PyUnicode_New."

Where i can find old release setup exe？

Any help would be appreciated.

Please post your full environment using set

Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding

This error does not come from xpra. As per this answer to the same error message, it's very likely that something in your environment is causing this problem. Another installation of python, a virtualenv, or something like it.

Try running with a cleaner path:

Path=D:\lua54\install\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;d:\LLVM\bin;D:\CMake\;in;C:\Strawberry\c\bin;C:\Strawberry\perl\site\bin;C:\Strawberry\perl\bin;C:\Program Files (x86)\Windows Kits\10\Windows Performance Toolkit\;D:\Rust\bin;D:\Git\cmd;d:\Bandizip\;D:\RTIDDS\rti_connext_dds-6.1.1\bin;C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin;C:\Program Files (x86)\MSBuild\14.0\Bin

Remove everything except the bare minimum:

SET PATH=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem

Not heard back, likely an environment problem.

[sunzhusz]

I also encountered the same problem on Windows 7. The PATH was clean and it still didn't work. The cmd reported the same error

[totaam]

@sunzhusz it's definitely an OS / installation / environment issue, check your anti-virus, apps installed, etc
