View Full Version : Run Time Error 75 Windos 7

7th-November-2017, 10:42 AM
I downloaded MAPCAL 3.45 on a Windows 7 64 bit laptop.

Error message 'Run Time 75' Path/File access error appears and mapcal closes when trying to configure any of the settings in MAPCAl configuration. i.e O2 lookup table, or dashboard menu
Also, Air/Fuel on dashboard is erratic and does not match the gauge readout.
I am runing an AEM wideband 30-4110 which is connected to the Analog # 1 white wire of the MAPECU3 16 way pin connector.

MAPCAL 3.3.2 still works fine with no error messages. Air/Fuel display values on MAPCAL dashboard and gauge match the display voltage on AEM Gauge.

We have run MAPCAL 3.4.5 on many Windows 7 computers, including 64-bit. It sounds like an installer problem or there is a config file missing or it is the wrong format. Did you install the new version into a new folder off C:\Program Files\, for example C:\Program Files\MAPCALV345\? Also, I assume you ran setup.exe to install MAPCAL V3.4.5?

Yes, I had run setup.exe.

Today, I removed the software and re-installed under a different folder.
It is working now. I am able to connect to mapecu3 and change the configuration.

Thank you.
