+| The application failed to load Tesseract OCR DLLs when hosted on IIS, resulting in the error:
+Could not find a part of the path 'C:\inetpub\wwwroot\VizarCore\x64'. |
+
+| Reason
+ |
+ * IIS couldn't load the required Tesseract and Leptonica DLLs because some system components were missing.
+* The Visual C++ Redistributables for VS2015-VS2022 (x86 and x64) were not installed.
+* IIS on a 64-bit server needs both redistributables to load native libraries correctly.
+* The application's folder paths and permissions were not properly set up for OCR binaries.
+ |
+
+
+| Solution |
+
+Installed Required Redistributables
+Installed both VC_redist.x86 and VC_redist.x64 for VS2015-VS2022 on the IIS server.
+Updated Server
+Applied all available Windows updates (including cumulative and Defender updates) to ensure system stability.
+Configured Application Paths
+Set default paths for OCR binaries:
+* C:\inetpub\wwwroot\myapp\Tesseractbinaries
+* C:\inetpub\wwwroot\myapp\tessdata
+Set Proper Permissions
+Ensured IIS_IUSRS group has Read & Execute and List folder contents permissions on the above directories.
+Observed Delayed Activation
+OCR functionality did not activate immediately-likely due to IIS caching or delayed DLL loading-but began working shortly after configuration.
