iTunes Error 7 (Windows error 193)

First I know there are multiple threads on this.

I am running W7 64-bit. Every time I try to install ITune I get an Error 7 (Windows error 193) upon completion ( and another pop up that says 'iTunes helper was not installed'). During the installation process I get a message that Apple Mobile Device Service was unable to start. To which I select 'Ignore'

Having read various threads on my problem I have

1) Gone to Windows Update and checked I have the latest updates.

2) Ensured I have the latest .NET Framework ( 4.5.2)

3) Uninstalled all Apple S/ware ( in the order recommended) except Safari. I also deleted any remaining Folders in Program Data, Program Files & Program Files (x86)

4) Run scan disc

5) Tried installs, after repeating (3) with my anti-virus s/ware switched off but I still get the same failure.

Any other suggestions?

Oh, and I also select 'Run as Administrator for the installation

Windows 7

When you right-click where? If you install 7-Zip then it should integrate with Windows Explorer.

Try again, right-clicking on the installer and selecting the Run as Administrator option.

Try the MS Installer Fixit, or if you have a 64-bit system try the "for older video cards" version.

I Uninstalled everything in the order suggested. Downloaded version 12.01.26 into 7 zip and installed each component individually. It worked and all my music was there. Thanks, you've been a big help.

This is the only fix that will work on windows 7 or 10. I worked hard for the past 6 moths doing everything this will work .

good luck

Navigate to
```
C:\Windows\System32
```
.
Locate the
```
msvcr100.dll
```
file.
Make sure that the file name is exactly
```
msvcr100.dll
```
. If you’re unable to locate
```
msvcr100.dll
```
, do not continue with these steps and do not move other files from this folder.
Drag the
```
msvcr100.dll
```
to the desktop. When prompted, click Continue.

After you drag the file to the desktop, try performing a repair on both installed versions of Apple Application Support (64 and 32-bit) in the Control Panel (iTunes requires both versions of Apple Application Support):

Click Apple Application Support 32-bit to select it.

Right-click Apple Application Support 32-bit to open the shortcut menu.
Select ‘Repair’ and complete the Repair Wizard.
Perform the same steps for Apple Application Support 64-bit.

Try to launch iTunes.
If there's still an issue, download a new copy of the iTunes installer.
Completely remove and reinstall iTunes and related software components from your computer. Then, reinstall iTunes.
If you still see the messages, restart your computer and try to launch iTunes again. If iTunes launches correctly, place the msvcr100.dll in the Recycle Bin and then empty the Recycle Bin.
If there's still an issue, contact Apple Supportfor more help.
