Hi paule_uk,
Thanks for providing us this information. I believe you are not installing the driver correctly. After transferring the file to desktop follow the steps below:
1.Double-click the new icon on the desktop labeled R*******.EXE.
2.The Self-Extracting window appears and prompts you to extract or
unzip to C:\DELL\DRIVERS\r*******. Write down this path so the executable (I.e.
Setup.exe) file can be found later.
3.The Self-Extractor window appears.
4.Click OK.
5.After completing the file extraction, if the Self-Extractor
window is still open, close it.
6.Click the Start button and then click Run.
7.Type C:\DELL\DRIVERS\r56237 in the Open textbox and then click OK.
8.Follow the on-screen installation instructions.
Note: R***** should be the respective file name.
If you have any further queries, please feel free to contact us.
Thanks and Regards
Sandeep P
