To perform successfully a manual reinstallation of your Avira Antivirus you have to perform first a cleanup of your current Avira Antivirus.

Hi, I need help had Avira Antivirus Pro installed on my old PC that was hit by lightning. My Insurer replaced it with a new HP PC. I cannot REMOVE the old device from my active Avira account. Error: "Hiccup! An error occurred. We could not remove this device."
If I use the same product key, it is still in use. The old damaged PC was taken by the insurer so I cannot uninstall. What do I do to use the product key again?

I needed to reinstall Avira and followed your procedure on how to do this. I tried to do a complete

cleanup by physically removing folders as advised in your page "How do I reinstall my Avira Antivirus

product?"

After completing the instructions I tried to install Avira and I received the following error message

<The feature you are trying to use is on a network resource that is unavailable.

Click OK to try again, or enter an alternate path to a folder containing the installation package

"Avira.OE.Setup.Msi.msi" in the box below>

The box below contained this path
C:\ProgramData\Package Cache\{316EB047-4627-4B63-B0A6-8CD32D07D962}v1.1.34.19732\

I then received this message

<The older version of Avira Launcher cannot be removed contact your technical support group.>

Any help with this would be much appreciated.

удалить C:\Program Files\Avira - отказано в доступе, открыть C:\Documents and Settings\All Users\Application Data\Avira - отказано в доступе, эту папку не возможно открыть, вы же это знаете, зачем даете такие дурные советы?
За что я платил деньги, если вместо платной версии мне установился free avira? и я теперь не могу его переустановить? Very BAD service!!!

It toopk 7 days my PC out of order , refresch PC reinstall all Softwares , But I can not install Avira Internet Security and Speedup , I bough 1 month ago . Only free version . I come to my Avira Register , my System Speedup Expiration date 2016.09.29 and Internet Security Suiter Exp. 2016.03.20. I can not install ,I bought on Avira online , no disk , no Serial number . Contackt to Support is slowly . Please help .

Как переустановить если у меня только серийный номер сохранился? У вас же значится мой продукт и толку от этого никакого.
Мало того что 2 службы весь год то работали то нет так ещё и не переустановить по человечески! Лицензионный файл хотя бы можете выслать?

Upon renewal of my AVIRA PRO license, update was not possible any more. I first got a message like this (in Italian):

<The feature you are trying to use is on a network resource that is unavailable.
Click OK to try again, or enter an alternate path to a folder containing the installation package "Avira.OE.Setup.Msi.msi" in the box below>.
The box below pointed to a folder nested in C:\ProgramData\Package Cache

The next message was
<The older version of Avira Launcher cannot be removed contact your technical support group.>

Then I followed exactly the procedure reported in the Answer "How do I reinstall my Avira Antivirus product?". It had no effect and I obtained exactly the same error messages.

What shall I do now??
