I get the error "@Memutils@_UpperCase$qqrx20System@UnicodeString not found in DLL dac140.bpl" after installing UniDAC 4.1 on RAD Studio 2010.

I've read in this forum and delete all *dac*.bpl, memutils.dcu, ... and install unidac again. The error still exists.

What can I do?
Delphi 2009 is installed on this PC too, together with unidac for D2009. Can this be the problem?

The second error is "Package C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\Bin\dclcrcontrols140.bpl can't be loaded", but this package exists...

Such problem shows that there are still files from the old UniDAC version on your computer. Please try the following:
- remove UniDAC;
- remove all *dac*.bpl and *crcontrols*.bpl files from your computer;
- remove *.dcu files from your project;
- reinstall UniDAC.
If it doesn't help, try the following:
- remove UniDAC;
- reinstall UniDAC with the /force parameter like this: unidac41d12pro.exe /force

It seems, I do something wrong at uninstalling. I do it again and it work.
Thank You for your advice!
