I recently installed LabVIEW 2013 on a computer (running Windows XP 32-bit). The machine also has LabVIEW 8 installed, which is what I was using prior to upgrading. I opened a VI that was created in LV8 and then saved it and all its subVIs in LV2013. Now when I open the VI in LV2013 and try to run it, a window pops up asking me to find the "lvruntimeeng.msi" installation package for LabVIEW Run-Time Engine 7.0. If I cancel that dialog box and the subsequent message stating that the installion files were not found, the VI appears (at least from intial inspection) to run normally.
I closed LabVIEW, downloaded Run-Time Engine 7.0 from the NI website, and tried to install it, but I received a message saying that it is already installed (as I had suspected). How can I determine what part of the VI and/or its subVIs is trying to make use of Run-Time Engine 7.0? Alternatively, how can I get LabVIEW to instead use the Run-Time Engine 2013 that was installed when I upgraded to LabVIEW 2013?
