[Python] how to solve Python error : pywintypes.com_error exception that i use for changing...

so I have this code that I used to convert an excel file ( .xls) to (.xlsx) and edit it and save it to another location.. it used to work perfectly but just now I encounter some Error with the xlmain11.chm? I don't understand the problem.. can someone help me?

this is my shorter code

import win32com.client as w3c
import time
class ConvertAndMoveExcel:
def __init__(self, year):
self.year = year
self.path_from = r"C:\Users\[name]\OneDrive\Queen Wifi\Download Sementara"
if self.year == 2024:
self.path_to = r"C:\Users\[name]\OneDrive\Queen Wifi\data E-ebill"
elif self.year == 2025:
self.path_to = r"C:\Users\[name]\OneDrive\Queen Wifi\data E-ebill 2025"

def file_name(self, server, data, month, paths, type):... #just a function to determine the file name location

def isruning(self):
proceses = psutil.process_iter()
for proc in proceses:
if proc.name() == "EXCEL.EXE":
proc.kill()
print("Excel is closed completely") #so I can see the log cause sometimes the excel was not closed properly
def save_file(self, path_from : Path, path_to : Path):
self.isruning()
xl = w3c.Dispatch('Excel.Application')
wb = xl.Workbooks.Open(path_from)
xl.DisplayAlerts = False
wb.SaveAs(path_to, FileFormat=51)
xl.DisplayAlerts = True
wb.Close(True)
xl.Application.Quit()
self.delete_file(path_from)
self.isruning()
def auto_save(self):
while True:
month = input("Month: {01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12} or exit: ")
if month == "exit":
break
server = [1391, 2107, 3119]
data = ["user", "income"]
for i in server:
for j in data:
print(f"Saving Server {i} {j} {month} on progress")
path_from = str(self.file_name(i,j,month,self.path_from,"xlx"))+"x"
print(path_from)
path_to = str(self.file_name(i,j,month,self.path_to,"xlsx"))
print(path_to)
if Path(path_from).exists():
self.save_file(path_from,path_to)
print(f"File {path_from} saved to {path_to}")
time.sleep(5)
else:
print(f"File {path_from} not found")

if __name__ == "__main__":
year = int(input("Enter the year: "))
convert_excel = ConvertAndMoveExcel(year)
while True:
asking = input("Save the file? : y/n ")
if asking == "y":
convert_excel.auto_save()
else:
break



the error in cmd
