I'd appreciate any help or guidance people might have in getting this issue resolved!
I have an experiment that was programmed in Inquisit Desktop 3 (circa Spring 2016). The nature of our experiment means that we have a copy of the experiment script for each participant (inefficient yes, but greatly helps me ensure that nothing gets lost/overwritten, since each participant has unique image stimuli). Our lab subsequently updated to Inquisit Desktop 5 [without me noticing, apparently] and the experiment files ran seamlessly in Inquisit 5. We did not update the file types (they are still .exp & .dat per Inquisit 3).
Due to lab schedule constraints, I recently moved this study to another lab room that did not have InQuisit installed. We were in a hurry to get the study launched + running, so I simply downloaded trial versions of InQuisit Desktop 4 and once again, the experiment files ran perfectly. However, our lab has an unlimited license for Inquisit Desktop 3 (and the trial versions of 4 are expired/expiring), so I downloaded Inquisit Desktop 3 from http://www.millisecond.com/download/archives.aspx.
On the first computer, I installed Inquisit 3 before uninstalling Inquisit 4 and found that Inquisit 4 could open the file, but I received an error message ("file not found"; see images below) when attempting to open files with Inquisit 3. Upon uninstalling Inquisit 4 and resetting the 'file open' defaults, I still received the same "file not found" error message. So, on the second computer I uninstalled Inquisit 4 prior to installing Inquisit 3 to see if that would make a difference. I was still unable to open the .exp & .dat files using Inquisit 3. I then tried copying experiment scripts that hadn't been run in Inquisit 4 to the computer to see if that would make a difference. It did not. [The file path is
correct; I also tried renaming the folder so it didn't have hyphens and that did not help either.]
So I seem to be stuck with Inquisit 3 being unable to open these files (both from Windows Explorer and via File --> Open within Inquisit).
Does anyone have any thoughts or intuitions of what might be occurring (and how to fix it)? I'd greatly appreciate suggestions. We have participants scheduled to run at 10 AM tomorrow and all the trial licenses will have expired by then.
P. S. Does Inquisit 3 require the installation of anything not bundled with it? [That wouldn't already be installed with via Inquisit 4?]Error Messages:
