IIS hosted VSTO word template opening failed from client computer.

[Lem]

I has simple VSTO office application (simplest word template), hosted on IIS
6, Windows Server 2003(application was published to specified location).

Published directory named "sample".
Its contains 2 files:
WordTemplate2.application,
WordTemplate2.application
and subfolder WordTemplate2_1.0.0.10.

Subfolder WordTemplate2_1.0.0.10 contains application config, manifest, dll,
and same 2 files - WordTemplate2.application and WordTemplate2.application.

Its manifest is:

<assembly xmlns="urn:schemas-microsoft-com:asm.v1"
xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" manifestVersion="1.0">
<assemblyIdentity name="WordTemplate2.dll" version="1.0.0.10" />
<asmv2:entryPoint name="Startup" dependencyName="dependency0">
<asmv2:clrClassInvocation class="WordTemplate2.ThisDocument" />
</asmv2:entryPoint>
<asmv2:dependency asmv2:name="dependency0">
<asmv2:dependentAssembly>
<assemblyIdentity name="WordTemplate2" version="1.0.0.0"
publicKeyToken="014534cd87c87179" />
</asmv2:dependentAssembly>
<asmv2:installFrom codebase="WordTemplate2_1.0.0.10\WordTemplate2.dll" />
</asmv2:dependency>
<asmv2:installFrom
codebase="http://192.168.111.111/sample/WordTemplate2.application" />
</assembly>

Its config file is (contains connection string to retreiving button text
form DB):
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
</configSections>
<connectionStrings>
<add name="WordTemplate2.Properties.Settings.VSTOConnectionString"
connectionString="Data Source=TestDB;Initial Catalog=VSTO;User
ID=sa"
providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>

When I'm trying to open the application from local computer
(http://192.168.111.111/sample/WordTemplate2.dot or
http://192.168.111.111/sample/WordTemplate2_1.0.0.10/WordTemplate2.dot),
its opened fine, and VSTO section is running ("press me" button appeared on
side of the document).

But when I am trying to open the same link from another client computer, I
receive following error message:

Failed to update customization from the specified deployment manifest.

I tryed to switch off CASPOL on the client computer - but it does not help.
I set security permissions on IIS to "sample" folder, and type user and
password during connection from client mashine - still does not help.
I also removed ".doc" and ".dot" MIMIE extensions from IIS - the same result.

Thanks a lot.
Evgeny.
