Dear all,
the V6.4, the hypersizer running is ok, but the V6.1.80 was installed the same computer after the V6.4 was uninstalled. there is an error when save the project:

Application Error in modMain::Validategroup [function]()
line #45, Error #-2147188737, Error in Section DLL: Error in the GROUP SIZING VARIABLE input file, *.GSV, lost position during read due to incorrect ordering.

why?
thanks

When you uninstalled v6.4, did you delete the HyperSizer Data\Projects\Temp folder? Try deleting the temp folder for the project that returned the error. Does the error message go away?
