Unable to connect Copter 4.05 on 32 bit MissionPlanner

I have a quadcopter with Pixhawk 2.4.8. Firmware fmuv2 installed using 64 bit windows pc. When I try to connect Pixhawk to 32 bit laptop it is looking to update driver. Does this sound correct. If so where do I find it ? I have not had any similar issues with previous firmware updates.
Any help would be appreciated.

Try this link to the driver.msi download: https://firmware.ardupilot.org/Tools/MissionPlanner/driver.msi

Thanks Shawn
I gave that a shot but still cannot connect. Reinstalled MissionPlanner with no change. The programme is not receiving the device id when trying connect. However it does work with windows 64 bit. I’ve checked GCS on android tablet which connected up OK.
Is there any conflict between Copter 4.05 and 32 bit Windows ? If not the problem may lie with the com ports ?
