Hi, thanks for the report.
Could you please state the version of pytket you have installed (the output of pip show pytket), and also details of the system you are running on (OS version, architecture)?

What about the architecture? Can you try

python -c "import platform; print(platform.architecture(), platform.uname())"

Note that only 64-bit is supported.

[yinxx]

python -c "import platform; print(platform.architecture(), platform.uname())"
('64bit', 'WindowsPE') uname_result(system='Windows', node='admin-PC', release='7', version='6.1.7601', machine='AMD64', processor='Intel64 Family 6 Model 60 Stepping 3, GenuineIntel')

Thanks. I am not sure what the problem is; however we have found that Windows installations can break for certain versions. Windows 7 is not an officially supported OS (we test on Windows 10), and we are unable to reproduce the issue as we do not have access to a Windows 7 machine.

Sorry I can't be of more help. Are you able to switch to a different OS (Linux, MacOS >= 10.14 or Windows 10) to run pytket?
