You might want to clear browsing history for Internet Explorer since it can accumulate over time. During an install of Acctivate Mobile on a Windows device, you might encounter one of the following messages: ``` Could not write to file:\Program Files\Acctivate\symbol.all.arm.cabInstall Failed ``` ``` Could not write to file:\Program Files\Acctivate\Acctivate.CABInstall Failed ``` These may indicate that your device doesn't have enough room to install the necessary files the application needs.  Try deleting unnecessary files such as old items in your Downloads folder.  You can try clearing the Browsing History for Internet Explorer using the following steps: 1. Open **Internet Explorer** 2. Tap the **Menu** button (four horizontal lines) 3. Select **Tools** then **Options** 4. Select **Browsing History** in the new screen 5. Select any history option you want to wipe such as **History** to highlight it 6. Tap the **Clear** button If you have sufficient install space on your Windows device and are still getting errors during the installation, [submit a support request](https://acctivate.com/support/#ticket) so that the Acctivate Support Team can assist you. -
