[c#] Vprašanje glede release verzije aplikacije

Spoštovani!

V Visual Studio 2010 Ultimate imam Solution, v katerem imam dva projekta. Prvi je dll knjižnica, katere namene je komunikacija z napravo. Pod to knjnižnico je še en dll, katere namen je podpora industrijskemu modbus protokolu. Drugi projekt v Solution-u pa je grafična aplikacija, ki prikazuje status te naprave z uporabo omenjenih dll knjižnic. Sedaj pridemo do problema: modbus knjižnico, ki smo jo kupili je spisana in prevedena v .net framework 2.0, moj dll ter aplikacija pa sta spisani v framework 4.0. Na googlu sem našel, da je treba dopolnitii app.config datoteko obeh projektov z

<startup>
useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>

in to sem tudi storil. Na development mašini v firmi zadeva deluje brez problemov. Ko smo šli pa na "release" mašino k stranki, sem na laptopu naredil finalni build solutiona, presnel vse potrebne datoteke na "release" mašino pri stranki in ko aplikacijo poženem, dobim sledeč error:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

Zakaj mi ne aplikacija ne dela na "release" mašini, mi lahko kdo pomaga? Release mašino sem tudi update-al, inštalirani so Windows XP Pro z vsemi nadgradnjami za .Net Framework 4.0. Programski jezik je c#.

Vnaprej se zahvaljujem za pomoč in s spoštovanjem,
M.

Lahko nastaviš tvoj projekt na framework 2.0

Hmm, hvala, to sem vse dodal, ampak ni delalo. Ko sem pa skopiral imeprograma.exe.config v "release" direktorij, je pa app zastartala, cudno ... Se ne da tega config fajla nekako "embeddati" v exe, ker imam notri connection string za bazo z vsemi "obcuteljivi" podatki (nekodiranimi) - username, pass, ....?
