Installing Skype failed; code 1601

Asked By 80 points N/A Posted on -


I am using windows vista 32 bit on my system.
I have been trying to install Skype on my machine but unfortunately I always get the following failure message:
Installing Skype failed; code 1601

The error is:


Installing Skype failed; code 1601

The windows Installer service could not be accessed. Contact

Your support personnel to verify that the windows Installer

Service is properly registered. 

I have been using chrome as well as internet explorer 9 but both end up with the same message.

Does anyone has any idea what should I do to remove this error and install it successfully.

I really need it urgently.

Please help me as soon as you can.

I'll be really thankful.

Hello Hunter,

I have a solution that might help with your problem.

I understand that you are currently running Windows Vista, and you want to install Skype successfully.

Solution One

The first thing I need you to do is to click the Windows Button on the lower left of your screen, then point your cursor to the “Search programs and files” box.

Search programs and files

Type %windir%System32msiexec /unregserver and click Enter.

Then on the same search box type %windir%System32msiexec /reserve and click Enter.

If this method does not work for you, you can try the following.

Solution Two

Click the Start (Windows) button on the lower left of your screen.

Go to All Programs, Accessories, System tools and select System Restore.

System restore

Once the System Restore program is open click next and find a previous restore date when your computer was running normally.

Restore your computer and wait until your system restarts. You should now redownload Skype and try to install again, good luck.

NOTE: System Restore can help you fix your problem, however, you might want to make a backup of important files on your system because you will be "Restoring" to an earlier date when your PC was working properly.

This error arises when Microsoft windows system files are not configured.

During updating Microsoft operating system or software that registers to the operating system could lead to this problem.

This problem can be resolved by fixing system files.

There are many applications that can be used to fix system files one of them is PC cleaner pro.

1. You can download from this link

2. Once it is downloaded install it and start scanning system files.

3. Once scanning is finished click on FIX ALL

4. Now reinstall Skype. It will be installed without error.
