3280262 - Event scripts with %USERPROFILE% or HKCU in the single file installer of Frontend products are not working correctly when copying files

Post configuration (on Installation end) event script set in the single-file self-installing .exe-package to install/deploy frontend products (SAP GUI, NWBC, Business Explorer, and so on)  using  %USERPROFILE% or HKCU is not working when trying to copy files using scripts as per below:

E.g. File "test.txt" can be copied from C:\test\ to C:\ProgramData\ folder with below script:
--------------------------------
strSrcFile = NwEngine.Variables.ResolveString("C:\test\test.txt")
strDstFile = NwEngine.Variables.ResolveString("C:\ProgramData\SAP\test.txt")
NwEngine.Shell.CopyFile strSrcFile, strDstFile
--------------------------------

But the file "test.txt" can't be copied  to C:\%USERPROFILE%\ folder with below script:
-----------------------------
strSrcFile = NwEngine.Variables.ResolveString("C:\test\test.txt")
strDstFile = NwEngine.Variables.ResolveString("%USERPROFILE%\AppData\Roaming\SAP\test.txt")
NwEngine.Shell.CopyFile strSrcFile, strDstFile
-----------------------------
