Rapid SCADA 4.5 can install without reported errors on Windows 8.1 64-bit while Scada-Admin still fails to open. When the other installed applications launch normally and Scada-Admin produces no window or error message, check the Microsoft SQL Server Compact prerequisite before replacing the operating system.
Recognize the Startup Failure
| Observation | Evidence-based interpretation |
|---|---|
| Rapid SCADA 4.5 installation completes without errors | A successful main installation does not confirm that both required SQL Server Compact runtime packages are installed. |
| Scada-Admin does not open or display an error | This symptom is associated with a missing SQL Server Compact prerequisite in the reported case. |
| Other Rapid SCADA applications open | The failure can be isolated to Scada-Admin rather than the entire installation. |
Install Both SQL Server Compact Runtimes
Open the Rapid SCADA prerequisites and execute both Microsoft SQL Server Compact installers. Do not treat the presence of only the 64-bit package as sufficient on a 64-bit operating system.
- Execute
SSCERuntime_x86-ENU.msi. - Execute
SSCERuntime_x64-ENU.msi. - Launch Scada-Admin again and confirm that its interface opens.
Do Not Assume Windows Is the Root Cause
The evidence documents the symptom on Windows 8.1 64-bit but does not establish that Windows 8.1 is unsupported. Install both prerequisite packages and retest before formatting the computer or replacing Windows with Windows 7.
Verify the Repair
The acceptance criterion is direct: Scada-Admin must open after both runtime installers have executed. If it remains silent, the available evidence does not identify another cause; record whether both installers completed and continue diagnosis through the product's official support channel rather than attributing the failure to operating-system compatibility without further evidence.
FAQ
Why does Rapid SCADA 4.5 Scada-Admin do nothing when opened?
In the documented case, Scada-Admin required the Microsoft SQL Server Compact prerequisite even though the Rapid SCADA installation completed without errors.
Which SQL Server Compact installers does Scada-Admin require?
Execute both SSCERuntime_x86-ENU.msi and SSCERuntime_x64-ENU.msi from the prerequisites.
Should I replace Windows 8.1 with Windows 7 when Scada-Admin will not open?
Do not replace the operating system based on this symptom alone. Install both SQL Server Compact runtime packages and verify Scada-Admin first; the evidence does not establish Windows 8.1 as unsupported.
