| Check | How to Verify | |-------|---------------| | | Double‑click the desktop shortcut or run C:\Program Files\MetaGeek\inSSIDer\inSSIDer.exe . The main UI should appear without error dialogs. | | License status | In the app, go to Help → License . The Office Enterprise license should be listed as Active . | | Service registration | Open PowerShell: `Get-Service -Name "MetaGeek

# Re‑register the service $regsvr32 = "$env:SystemRoot\System32\regsvr32.exe" & $regsvr32 /u /s "$env:SystemRoot\System32\msi.dll" & $regsvr32 /s "$env:SystemRoot\System32\msi.dll"

If you experience any of the above, proceed with the diagnostic flow chart below. | Category | Likely Cause | Evidence | |----------|--------------|----------| | Corrupted installer package | The downloaded .exe or .msi is incomplete or has been altered by a proxy/antivirus. | Hash mismatch (SHA‑256) when compared to MetaGeek’s published checksum. | | Blocked system files | Windows Defender, third‑party AV, or corporate AppLocker blocks the installer from writing to %ProgramFiles% or the temporary folder. | Event Viewer shows Win32/AV or AppLocker events. | | Pending Windows updates | A pending reboot or incomplete feature‑update leaves the Windows Installer service in an inconsistent state. | msiexec returns error 0x8007000C. | | Legacy .NET runtime | inSSIDer 4.x depends on .NET Framework 4.7.2 . Machines only having 4.5 or 4.6 may crash the custom bootstrapper. | Crash dump shows System.IO.FileLoadException for System.Runtime.InteropServices . | | Conflicting previous versions | Leftover files/registry entries from an older inSSIDer (e.g., 4.3.x) cause version‑check failures. | Log file ( inSSIDer_Install.log ) contains “Existing installation detected, version mismatch”. | | Insufficient permissions | The user is not a local admin, or UAC is set to “Never Notify”. | Installer fails at “Creating program folder” with error 5 (Access denied). | | Bad temporary folder | The system’s %TEMP% path points to a full or encrypted drive. | setup.exe cannot create temporary extraction folder, error 0x80070070 (disk full). |

| # | Action | How to Perform | Expected Result | |---|--------|----------------|-----------------| | 1 | | - Right‑click the downloaded inSSIDer_Office_Enterprise_4.4.0.6_Setup.exe → Properties → Digital Signatures → Verify the signer is “MetaGeek, Inc.” - Open PowerShell and run Get-FileHash <path>\setup.exe -Algorithm SHA256 and compare with the checksum published on the download page. | Signature is valid, hash matches. | | 2 | Run as Administrator | Right‑click the installer → Run as administrator . | Installer launches with elevated token. | | 3 | Temporarily disable AV | Open Windows Defender / third‑party AV console → Real‑time protection → Off (or add an exclusion for the installer folder). | AV no longer interferes. | | 4 | Check AppLocker / Software Restriction Policies | Run secpol.msc → Application Control Policies → AppLocker → Look for rules that deny setup.exe or any .msi in the download path. | No deny rules present. | | 5 | Confirm .NET 4.7.2 is installed | Open Control Panel → Programs → Turn Windows features on or off → expand .NET Framework 4.8 Advanced Services → make sure .NET Framework 4.7.2 (or later) is present. Or run reg query "HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" /v Release – value ≥ 461808 = 4.7.2+. | .NET runtime present. | | 6 | Look for pending reboot | Run shutdown /a in an elevated command prompt (no output means no pending reboot). Or check Windows Update → Restart required . | No pending restart. | | 7 | Clear temp folders | Delete everything inside %TEMP% and C:\Windows\Temp . | Temporary directories empty. | | 8 | Remove previous installation remnants | - Uninstall any older inSSIDer version via Settings → Apps . - Manually delete C:\Program Files\MetaGeek\inSSIDer (if it exists). - Delete registry keys HKLM\SOFTWARE\MetaGeek\inSSIDer and HKCU\Software\MetaGeek\inSSIDer . | No leftover files or keys. | | 9 | Check free disk space | Ensure at least 2 GB free on the system drive (C:). | Sufficient free space. | |10| Enable Windows Installer logging | Run msiexec /i <path>\inSSIDer_Office_Enterprise_4.4.0.6.msi /l*v "%TEMP%\inSSIDer_Install.log" (replace <path> ). | Log file created for deeper analysis. |

This article consolidates the most common root causes, step‑by‑step troubleshooting procedures, and permanent work‑arounds that have been verified by MetaGeek’s support engineers and the wider community. | Symptom | What you’ll see | When it occurs | |---------|-----------------|----------------| | Installer window disappears | The “Setup – inSSIDer Office Enterprise” window closes abruptly, sometimes with a Windows error dialog (“Program has stopped working”). | Immediately after clicking Install or during the “Copying files…” stage. | | Progress bar stalls | The bar stops moving for more than a minute; the “Cancel” button is grayed out. | During the “Installing components” step. | | Missing shortcuts | After the crash, the desktop and start‑menu shortcuts are not created. | After the installer terminates. | | Registry remnants | Keys under HKLM\Software\MetaGeek\inSSIDer remain even after a failed install. | After multiple attempts. | | Event Viewer entries | Application error with source msiexec.exe or setup.exe , error code 0x80070643 . | In the Windows Event Log. |
