Required permissions cannot be acquired. / Failed to grant minimum permission requests

התקלה הזאת מתרחשת כאשר רצים קבצים באתר (DLL וכו') שאינם נחשבים כ FULL TRUST , במערכת ב .net , שמשתמשת ה ASP.

לאחר שהגדרתי את האתר ב IIS 7 ניסיתי להריץ אותו ב LOCALHOST אבל קיבלתי הודעה כזאת:.

מסתבר של .NET יש הרשאות משלו במיוחד שמדובר על FRAMEWORK 2 , הוא לא מתייחס בכלל להרשאות שמוגדרות ב IIS 7.

אז איך מתקנים את זה:
ב WINDOWS 7 נראה כאילו שלא קיים FRAMEWORK 2 וה DEFAULT הוא 3.5, אם במקרה אתם רוצים להתקין אתר שבנוי ב FRAMEWORK 2 תצטרכו להוריד את ה .net framework 2.0 configuraton שנמצא בחבילת ה SDK
של framework 2.0
לאתר מיקרוספט

הכלי נמצא
 CONTROL PANEL -->ADMINISTRATOR TOOLS -->.NET FRAMEWOR 2.0 CONFIGURATION


תחילה נבחר ב RUNTIME SECURITY POLICY ונבחר ב ADJUST ZONE SECURITY


ניתן להגדיר הגדרות אבטחה עבור משתמש או עבור כל המכונה.


ונסמן את האפשרות של FULL TRUST

ולאחר מכן לסיים את ה WIZERD ולנסות להפעיל את האפליקציה שוב.
