I am on the same boat (64-bit AVs). I had to make a few changes to AlphaSkins but I am still wondering why this happens now. Is it Delphi 11.1 causing issues?
My changes for AlphaSkins are:
acgpUtils.pas:
748:gpaPColor := Pointer(PAnsiChar{Integer}(bmData.Scan0) + Y * bmData.Stride);
acShellCtrls.pas:
4344: // InitSystemImageList;
sGraphUtils.pas:
7506: with PRGBQuad(PAnsiChar{Integer}(srcLine) + Pixel)^ do begin
But after that I have issues with other 3rd party components and it is a huge swamp… I think I will install Delphi 11 and test if 11.1 update is causing these issues.
Go to project options, then delphi compiler->Linking, turn off support high-enropy 64bit and you won’t get this error.
