Windows 7: File association problem - baffled

win7 Pro - 64
File association problem - baffled

(Win 7 - 64 on my desktop machine)

I've been extracting new versions of Irfan View for many yrs now but they now apparently only offer an installable option. I installed ver 4.44, monitoring the install with Regshot 2, and it overwrote all of my custom image file icons. So I built a reg file to fix this and merged it. Now clicking on a jpg opens Win Photo Viewer. Hmmm. All of my file associations look correct. Running FileTypesManager shows Irfan View as the default app as does Win Default Programs.

OK I export the few Irfan View keys that I think I really need and build an install.reg. Next I "uninstall" Irfan View by deleting all references to Irfan View in the reg and then merge my install.reg. FileTypesManager shows Irfan View correctly registered as does Win Default Programs. .bmp's and gif's now work correctly, opening I-View. But jpg's, png's & ico's still open in Win Photo Viewer. Rt click on a jpg, choose "OPEN WITH" > choose and Irfan View is already preselected. I click OK and it opens Win Photo Viewer !!! Welcome to the Alternate Universe.

I went into HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts and deleted all "user choice" entries for image files. Didn't help.

Here's my install.reg file:

Windows Registry Editor Version 5.00




@="\"C:\\Kosmo\\Apps\\Graphics\\I-View\\i_view32.exe\" \"%1\""




@="\"C:\\Kosmo\\Apps\\Graphics\\I-View\\i_view32.exe\" \"%1\""







@="GIF Image"


@="\"C:\\Kosmo\\Apps\\Graphics\\I-View\\i_view32.exe\" \"%1\""



@="\"C:\\Kosmo\\Apps\\Graphics\\I-View\\i_view32.exe\" \"%1\""

@="JPEG Image"


@="\"C:\\Kosmo\\Apps\\Graphics\\I-View\\i_view32.exe\" \"%1\""

@="Bitmap Image"



@="\"C:\\Kosmo\\Apps\\Graphics\\I-View\\i_view32.exe\" \"%1\""

@="PNG Image"


@="\"C:\\Kosmo\\Apps\\Graphics\\I-View\\i_view32.exe\" \"%1\""


@="\"C:\\Kosmo\\Apps\\Graphics\\I-View\\i_view32.exe\" \"%1\""

"DisplayName"="IrfanView 4.44"
"Publisher"="Irfan Skiljan"
Any ideas?

Welcome to sevenforum OPti3020

Do you understand how Registry HKEY works.
Certain keys /names are duplicate from another HKEY.
A careless change to the operating system configuration in the Registry could cause irreversible damage.
There is a need to understand how Registry work and how to made the changes.

Before doing the changes, you need to export the full registry.
After the registry is open, click on the Menu to Export the full registry file in case of problems start pop-up.

How long have you using this Irfan View program.
There is no need to touch the Registry to make changes on file association for Irfan View.

Refer to the picture as shown below.
The picture is open by; Menu --> Options --> Set file associations....
