Chtěl jsem si ten service pack nainstalovat na Autocad LT 2011 a píše mi to chybu že Service pack nebylo možné nainstalovat, očekávaný Autodesk produkt nebyl na vašem počítači nalezen. Co s tím?

Nepřekoukl jste se - instalujete opravdu SP1 pro LT2011? Instalujete 32bitovou nebo 64bitovou verzi SP1 podle toho jaký LT používáte?

Omlouvám se, bylo to překouknutí verze 32/64-bit. Už to funguje.

Pozor, Autodesk dočasně odstranil SP1 pro AutoCADy 2011, protože se u několika uživatelů objevily problémy se stabilitou aplikace.
 
SP1 ve verzi z 23.8. proto neinstalujte - vyčkejte prosím na uvedení aktualizované verze SP1. Pokud máte SP1 již nainstalován a nepozorujete problémy, můžete jej nadále používat. V případě, že problémy byly opravdu vyvolány Service Packem, zveřejní Autodesk opravný hotfix.

Pro ty, kdo instalovali SP1 v jeho původní verzi z 23.8., doporučujeme aplikovat hotfix opravující možnou nestabilitu Správce hladin:
http://usa.autodesk.com/getdoc/id=DL15629571
 
(nová aktualizovaná verze SP1 bude znovuuvedena během několika dnů)

Aktualizovaná verze SP1 - označená jako "SP1.1" (resp. "Update 1.1") - je k dispozici ke stažení (viz stránka Download).
 
Tento Service Pack aktualizuje AutoCAD 2011 a LT 2011. Pokud jste již instalovali původní SP1 (a nenainstalovali jste si výše uvedený hotfix), odinstalujte SP1 a nainstalujte SP1.1.
