ir7.00 Privileged instruction, works with older version?

[dblaker]

I'm running IR7.00 on a Dell desktop with Windows XP with SP2. I am the administrator. I have a home made simple parallel interface cable on LPT1 from the motherboard.

When I try to access the interface (either by check interface or download) I get a dialogue box ir, privileged instruction. IR7.00 did work until earlier this evening. I was trying programming a remote when it stopped working.

Interestingly when I do Interface -> Parallel -> 378 and OK, the setting doesn't stick. Meaning the selection isn't checked. Earlier this evening when things first stopped working those steps would give the same privileged instruction error.

I have an old version; IR 5.15 in another directory. And it works! This would seem to rule out cable, battery or port setting problems. Still I'm unsure if its an XP problem or something with my install of IR7.00.

In the IR7.00 directory is gwiopm.sys and two other dlls. I tried running unzip on the IR7.00 download and putting it in a different directory and it gives the same results. When I start ir I get a message saying ExtInstall directory doesn't exist, but I don't think this is related. I don't have any printer connected to LPT1.

I hope I haven't overlooked the answer to this problem in FAQs and searches. I tried allowio.exe but it didn't help. Are there some settings in the registery or else where that could have changed on me?

Thank you,
David B.

One other note, the last thing I did before it stopped working was running two instances of ir7.00 at the same time. (I was trying to compare one remote to another.) I don't know if this would make any difference.

We have seen the privileged instruction error occur when the IR7 Registry settings were in an inconsistent state(i.e. it pointed to a device type that you didn't have access privileges to).

To delete or clear all the Windows IR7 registry settings,
Create a ir7_reset.reg file containing 3 lines and then double-click the file
to execute it:

Code: Select all

REGEDIT4

[-HKEY_CURRENT_USER\Software\UEIC]

You can also try deleting
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\IRFile

the other thing that has caused this for me on a WinNT (XP, 2K, etc) platform is when you don't have write priv's to the directory where IR is trying to save the configuration file.

(or it's not there)

This has happened to me when I had IR on one machine, copied it to a flash drive on another and then tried to run it and the place where IR was looking for the config info is no longer there.

Thank you binky123. The registery edit file worked.

Do you think running two instances of IR cause the problem? I was trying to see settings in one remote to make updates to another that was a different model.

It should be ok to run two instances of IR7. The latest IR is IR7.01.
