Fixing a computer with a BIO metrics for drug test

I have customer who own a clinic, she call me up to repair their PC which they use for drug testing.

She want me to backup all the file and the software they use on their blood test, They used MSQL system to connect and upload record to DOH server (DTO). The PC is allready repaired by other technician 3 times and they backup all file, But the software or program they cannot make it run so the the customer allways go to Makati to reinstall the program 3 times.

The challenge here is I'm gonna make the system or program run with no wipe-out file or blood test records.

The DTO biometrics system include:
USB Fingerprint Scanner w/ USB Dongle by DigitalPersona
A4tech Camera

DigitalPersona is the license product compatible with the system use by DOH I think its was 16,000 each.

I have no problem with all client record because its all on the MSQL all I gonna do is copy the MSQL by making the hard drive as a slave on other PC.

I back up 4 folders:
DTO
digitalpersona
MSQL
usb fingerprintscanner

After doing backup files I reformat the PC with a OEM windows XP. Then I reinstall programs the only problem i found is the driver for usb fingerprints scanner it should be blue light on when it work, I thought it was already include on the dongle so i download it on digitalpersona website.

Restore all backup in the folder - I run the computer on safe mode then copy paste all the file .
(you must run on safe mode to copy all file because you can't copy while the system is running)

Testing the system require a internet connection at first run , the problem is they use smartbro and their is no connection or the connection is to slow " pop out message cannot establish connection to the server " so we test the pc on computer shop.

The system works !! the client was happy..
