iU22 software version 6.0.0.845 required

Hello, we have Philips iU22 device, the device in the beginning had a broken FHD monitor and after we replaced the monitor, the device started to give an error on the start up that hardware is not compatible, the original software version was 6.0.0.845 but drivers version or COTs were very old like 24, so we installed new software version 6.3.6.343 with COTs 49. so the error of incompatible monitor or hardware was bypassed and license was restored. But the touch screen still needs to be calibrated, and every time we try to enter the tech admin by service key in super user section, the device gives error after it starts the tech admin. internet explorer error and this shut down the window of tech admin. so I was doubting that the new application version 6.3.6.343 might be the reason, so I was looking for software that has application version of 6.0.0.845. So kindly if anyone has that version let me know
Best Regards
