From various several instances it has been observed that when users try to install Microsoft Office 2013 or upgrade to it from a previous Office version, they come elbow to elbow with “Microsoft Setup Bootstrapper has stopped working” error. Bootstrapper is an application (executable) designed to initialize the installation and setup of a program like Microsoft Office 2013. The application may experience trouble when it finds that a beta edition of Office 2013 exists, some hardware is not supported, that the minimum system requirements are not met, registry error(s) are there in Windows Registry, or that an antivirus or firewall program is under the impression that the installation file is a malicious executable file. For the purpose of installing Microsoft Office 2013 without hitches and glitches, here are a few workarounds which will help you do so.
Step 1: Locate & Remove Any Previous Office Edition
In most of the Bootstrapper errors it has been observed that the existence of a beta/previous Office edition plays as the disturbing/err element. So cancel the installation of Office 2013 and look for its beta version or a previous Office edition in <Programs and Features> in Windows 7 or Windows 8. You can use the Start Search bar in Windows 7 to search for “Programs and Features”. If you are using Windows 8, press the <Windows> key and start typing “Programs and Features”. Under “Programs and Features”, look for Microsoft Office entry, select it and then click <Uninstall>. When prompted, confirm the action and follow rest of the on-screen prompts to completely get Microsoft Office rid of your computer. When prompted, restart your computer to complete the uninstallation.
Though it’s not binding but you can run a registry cleaner to clean up any leftover registry entries, and keys and subkeys etc. of the uninstalled Microsoft Office program. Before you run the registry cleanup, backup your Windows Registry to undo any unfavorable changes. You should also find and delete all Microsoft Office files from Windows Explorer and other locations. Thereafter you can begin with the Office 2013 installation again.
P.S. Do not forget to make hidden files & folders show up in the Folder Options. Doing so will help you locate all the hidden Microsoft Office installer files and folders required for deletion.
Step 2: Disable Antivirus/Firewall Temporarily
As said above it is a natural behavior of an antivirus program or a firewall application to scan and block any executable file considering it the potential carrier of a malicious infection. So stop the installation of Office 2013 and disable the real-time scanning feature in your antivirus program temporarily. If you have a firewall (third-party), disable it temporarily. You should also disable Windows Firewall to let the Office installation file run properly. Once you have disabled your antivirus/firewall program, re-run the Office installation file and no Bootstrapper error should come up again.
Step 3: Install Office in Clean Boot Mode
Bring up the Run utility by pressing the <Windows> + <R> keys simultaneously on the keyboard. Type “msconfig” in the blank field and hit <OK>. In the System Configuration Utility window, highlight the <Boot> tab and deselect the <Safe Boot> option. Now highlight the <General> tab, check the <Selective startup> box, and uncheck the <Load startup items> box. Now highlight the <Services> tab, select the <Hide all Microsoft services> option, and click the <Disable all> button. Now click the <Startup> tab, click <Open Task Manager>. On the Task Manager window, right-click each enabled startup item and click <Disable>. Click <OK> and then select <Restart>. All third-party software and services including startup programs will be disabled now, helping you to run the installation file error-free. When done, locate the Office 2013 installation file and run it. Follow the onscreen prompts to complete the installation. When prompted, restart your computer normally.
Step 4: Install the Latest Software Updates
Make sure that you are running the latest Windows updates and additional software updates for the connected peripherals etc. Outdated applications may pose errors during the installation procedure. So stop the installation and then download and install the latest Windows updates for your Windows OS and other software installed on your computer. When done installing all updates, disconnect all peripherals and then begin with the Office installation procedure again.
Step 5: Modify Windows Registry
Locate and remove the “AppCompatFlags” registry key from Windows Registry. Open Registry Editor by typing “regedit” in the “Run” box and clicking “OK”. When Registry Editor opens, browse to HKEY_LOCAL_MACHINE> SOFTWARE> Microsoft> Windows NT> CurrentVersion> AppCompatFlags. Before you delete “AppCompatFlags”, you should back up it. To back up the “AppCompatFlags” key, right click it and click “Export”. This will open up the Import and Export wizard. Back up this key and when done, right click “AppCompatFlags” and select “Delete”. When prompted, click Yes to confirm the action. Exit Registry Editor and then begin with the Office 2013 installation again.
After having applied any of or all these steps, the Bootstrapped error should be fixed and the installation should complete successfully. Should you continue facing the Bootstrapper error or additional problems, call us at +1-877-907-4935 and get an expert to help you.
