Script to check Flash version isn't really checking version

Script to check Flash version isn't really checking version

I need some help making the following work. It's worked before (with other
software), but in the case of Flash, it isn't. What I'm trying to
accomplish is checking the installed version of Flash. If the installed
version of Flash isn't what I want, I want the script to uninstall the
current version and install my desired version.
:: Check Flash version and install if not matching.
:: Set version to check for.
SET latestVersion=11.5.502.135
SET
key="HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Adobe
Flash Player Plugin"
for /f "tokens=3 delims= " %%G in ('reg query %key% /v DisplayVersion
^| findstr /i current') do (
echo %%G
if %%G EQU %latestVersion% goto END
if %%G NEQ %latestVersion% goto Install
)
:INSTALL
:: Kill IE & FF
taskkill /f /im iexplore.exe /im firefox.exe
::Uninstall Flash
\\path-to-server\Flash-FF-11.8.800.94.exe -uninstall
:: Install Flash for Firefox
\\path-to-server\Flash-FF-11.5.502.135.exe -install
:: Install Flash for IE
\\path-to-server\Flash-IE-11.5.502.135.exe -install
:: Kill Flash updating
COPY /y \\path-to-server\mms.cfg C:\WINDOWS\System32\Macromed\Flash\mms.cfg
:END
The problem is that it's not reading the version that's installed. Instead
of echoing something like 11.5.502.135, it's echoing "%G". And since %G
does not equal my desired version (11.5.502.135) it's installing every
time.
So narrowing it down, the following is my problem:
for /f "tokens=3 delims= " %%G in ('reg query %key% /v DisplayVersion
^| findstr /i current') do (
echo %%G
if %%G EQU %latestVersion% goto END
if %%G NEQ %latestVersion% goto Install
)
When typing it out manually, as long as I stop at "DisplayVersion" I get
the info I'm looking for. But once I proceed to the last part of what's
inside the (), that's when I get the errors.
Any help sorting this out would be greatly appreciated.
