No, this should not be an issue. Our installer will successfully install the "Writing Tools" here in this case:
%ProgramFiles%\Corel\Shared\XMetaL\Writing ToolsIf you do not find that folder with the "writing tools" software installed then you may be running on 64-bit Windows 7. In this case you should check here:
%ProgramFiles(x86)%\Corel\Shared\XMetaL\Writing ToolsNote that 64-bit versions of Windows are currently not officially supported (up to and including all versions of XMetaL Author 6.0). Official support is coming with our 7.0 release. If you do have issues running the software on 64-bit Windows 7 please see:
