function 'FTC_CMapCache_Lookup' not found
Dear developers,
I tried to install micro-sam with the windows installer and when trying to run it I get the following error: function 'FTC_CMapCache_Lookup' not found
Any idea what is wrong?
Thanks and best Matthias
I cannot see more or do you mean the traceback?Von meinem/meiner Galaxy gesendet -------- Ursprüngliche Nachricht --------Von: Constantin Pape @.> Datum: 05.09.24 18:47 (GMT+01:00) An: computational-cell-analytics/micro-sam @.> Cc: mocherry @.>, Author @.> Betreff: [EXTERN] Re: [computational-cell-analytics/micro-sam] function 'FTC_CMapCache_Lookup' not found (Issue #683) Can you please post the complete error message here?

Hi @mocherry,
Thanks for reporting the issue. It seems that "freetype.dll" is causing the core issue.
Could you please confirm if you still face the issue with the Windows Installer? If not, I'll add a few mentions which might help us understand the issue better.
- Can you tell us your windows system configuration? (is it 64-bit or 32-bit)
- There is a scenario possible that while installing
micro-samusing the installer, 'freetype.dll' did not install properly, or potentially needs an upgrade. In case it still interests you, could we ask you to reinstallmicro-samusing the latest installer links in our documentation?
Let us know how it goes.
