function 'FTC_CMapCache_Lookup' not found

[mocherry]

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

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-sam using the installer, 'freetype.dll' did not install properly, or potentially needs an upgrade. In case it still interests you, could we ask you to reinstall micro-sam using the latest installer links in our documentation?

Let us know how it goes.
