Ok, found the problem in Tools>Options>Environment Variables, Changed the User System Overrides TEESRCPATH variable as follows: E:\Steema Software\Steema TeeChart Pro VCL FMX Source Code 2024.40\Source to: E:\Steema Software\Steema TeeChart Pro VCL FMX Source Code 2024.40\Source\VCL This variable is...

The code pointed to is in TeCanvas.pas:

I'm getting the same problem compiling for win32 in Windows 10 in Delphi 12.1 Patch 1; win32 compilation in Windows 11 works normally. Putting 'VCLTree' in Options Unit Scope Names makes no difference. The library paths in both W10 and W11 installations are identical: E:\Steema Software\Steema TeeCh...

Ok, never mind. The problem was finger trouble on my part. Sorry to bother you.

Hello,

Tried that a couple of times, but I get the same error. After aborting the failed installation, the installation folder is empty.

Andrew

Well, it installs ok on my HP laptop but fails on my Desktop with the error message shown. Any clues from the error? Install_error.JPG The error appears immediately after the customer Number and Passwords have been entered. Interestingly, the Desktop's installation folder contains a TeeCalc folder w...

Cannot install this. See Error: Using Delphi 10.4.1 in W10 Pro.

Hello Ed, Sorry to butt in again, but (ref your comment about different font sizes on my chart) I found the reason that the sizes were very different at 175% was that I had the Axis Labels using Verdana and the Titles using Segoe UI. Hadn't noticed that all these years! Hope you get your issue resol...

Actually, measured them at 100 and 175% with a ruler and they are scaled up. So please ignore my comment.

Thanks, Andrew

However... Just noticed that, although there is now no overlapping between axis titles and labels, the axis titles now aren't scaled up at 175%! How do I fix that?

Andrew

Well, as described in my 'TChartPageNavigator and High DPI' post, my problem was having the wrong settings in the Chart>Axis properties. Ok for 100% scaling but not for 175% or greater. Clearly different to this issue. Apologies for the 'red herring'.

Andrew

Found the problem. The Chart>Axis>Left/Bottom>Labels>Size settings were 33 and 27 respectively. These were fine for 100% scaling but not for 175%; setting them both to 0 fixed the problem. I wouldn't have found this problem if I hadn't been able to compare all my properties and settings with the one...

Well, I tested at W10 Pro (with latest updates) Display Settings>Scale and Layout>175%. It looks as though Ed's customers may be using a different method to increase Font size only? I can't actually find the method he shows in his message. So I'm not sure my results are relevant to him or not.

Hi Christopher, I replied a few hours ago, but my message seems to have disappeared. Your demo works perfectly at 100% and 175% when compiled here by 10.4 with patched 1 - 3. So it looks as though there is a problem with my environment or code. Thanks for your help in progressing this issue. I'll ge...
