Windows 7 EPSON WP4535 Scanner installation problem

I have a new desktop running Windows 7 Home Premium - 64 Bit. I have purchased an EPSON WP4535 all in one printer which installed fine apart from the scanner. I get a very similar issue to one on the Epson website whereby I get an error during the installation. However, the message on the Epson website says "Could not copy files". I get the error "Could not create files".

I should first of all say that the first attempt to install does not get past first base and gives the message -

Could not create "c:\Users\XXXXXX\LOCALS~1\Temp" - unzip operation cancelled.

I have seen this error before so to get around this I renamed the file from .EXE to .ZIP and manually extracted all the files. I even tried copying them to the folder that it appears to require them in - LOCALS\TEMP. Running the SETUP.EXE file gives the error:

An error occurred during setup. Restart your computer, then run setup again.

When I click OK I then get...

Could not find files required for setup. Check the setup disc, then run setup again.

The above message is subtly different from the one on the EPSON website which says "Could not copy files".

Nevertheless, I have followed the instructions on the Epson website, just in case it resolved my problem - but it didn't.

To confirm - I am logged on as Administrator.

I have also tried changing the system variable to point at an alternative TEMP folder but still get the same issue. I have also tried creating a new account, set as administrator and run the install from there - same error. I have tried altering the permissions on the folder - same error.

I have tried installing on a separate machine and it works so I know the driver is okay.

It sounds as though something has got messed up in the registry but I'm not sure what.

Anyone got any ideas?

 

Similar problem on a Dell with a Dell printer installed, printer worked fine but not scanner. Opened Device Manager, found the scanner listed but no driver available. Right clicked listed scanner w/o driver, chose to update driver and let Windows search for and install it...

 

"LOCALS~1" (LOCALS~1\Temp) in this case is the 8.3 name for "Local Settings" (Local Settings\Temp).

Do you have a Temp folder in there, and does it have full permissions?

 

SOLUTION THAT WORKED FOR ME:

If you are using windows 7, a fix can be to alter the TEMP and TMP variables.

Rightclick on 'Computer' and choose 'Properties'
Choose 'advanced system settings'
Click on 'Environment Variables'
Click on 'TEMP' and choose 'Edit ...'
Replace text with "c:]windows\temp" and click 'OK'
Click on 'TMP' and choose 'Edit ...'
Replace text with "c:]windows\temp" and click 'OK'
Click twice on 'OK' and close screens.
Run Setup.exe and it should install Epson Scan software.

Good luck!
