Why do I get "Failed to create COM object EasyXLS.ExcelDocument: Invalid syntax" error in PHP?

The following error might occur at runtime when using EasyXLS Excel library for PHP:

Fatal error: Uncaught com_exception: Failed to create COM object 'EasyXLS.ExcelDocument': Invalid syntax.

at line:

$workbook = new COM("EasyXLS.ExcelDocument");

Possible reason: EasyXLS.dll is not registered

If you did not have administrative rights when you installed EasyXLS, it is possible that the COM+ registration was not accomplished during installation.

To check this situation, go to Control Panel -> Administrative Tools -> Component Services. See if EasyXLS is present in Console Root/Component Services/Computers/My Computer/COM + Applications.

EasyXLS component in Component Services

If it is not present, EasyXLS must be registered using specific commands for EasyXLS 32-bit and EasyXLS 64-bit. Run as administrator one of the following command lines from Command Prompt:

EasyXLS.dll 32-bit

C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\regsvcs "<EasyXLS install path>\COM+ version\DLL\EasyXLS.dll"

EasyXLS.dll 64-bit

C:\WINDOWS\Microsoft.NET\Framework64\v4.0.30319\regsvcs "<EasyXLS install path>\COM+ version\DLL\EasyXLS.dll"

Regsvcs.exe can be stored in a different location if you have a different version of Microsoft .NET Framework installed on your computer. The above path is the default location for version 4.0.
