@SYMTestCaseID APPFWK-APPARC-0100

@SYMDEF INC127312

@SYMTestCaseDesc This test verify that apparc can dynamically upgrade and use an Ecom recognizer plugin.

@SYMTestPriority High

@SYMTestStatus Implemented

@SYMTestActions:
	
	1. Try to recognize .upg file with version 1 of recupgrade ECOM plugin but if shuld not be able to recognize as it is implemented like that
	2. Install version 2 of recupgrade plugin (copy recupgrade_winscw/armv5_rec.dll and recupgrade_1.rsc from z:\system\data to c:\sys\bin and c:\resource\plugin respectively)

	3. Because of installation Apparc will be notified and it will reload all recognizers plugin
	4. Now try to recognize .upg file . it shuld be able to recognize as vertion 2 is implemented like that

@SYMTestExpectedResults Test should complete without any leave, panic or error.
